    For those upset. The fact that the Ed Fong is 2 SNR stronger than the N9TAX doesn't make the N9TAX antenna bad. I really like it. Further, 2 SNR isn't even half an S-Unit. There should be no golden calves in ham radio. If you have issues with my test methods, spell it out and I'll either incorporate your comments or explain why I disagree.
    Thanks!

    Thank You for testing the N9TAX. I can almost buy two N9TAX antennas for the price of one Ed Fong. Huge plus there. You didn't mention price. The N9TAX can be had with just about any fitting with 18" of coax for $30.00 (a steal for the price). The N9TAX also has a ferrite built in. The Ferrite that the N9TAX includes might be a big bonus when running higher power. A choke is something you want on a J Pole design antenna. Both are great antennas. The N9TAX is slightly larger. Not a problem for me, it might be for some. I have no experience with the Ed Fong, but have had a N9TAX 2m/70 cm antenna up for 2 years that I use when running net control for bike races as a second antenna for my 2nd radio. It has held up in the rough weather and performs fantastic on both 2 meters and 70 cm. The build quality is excellent. The price savings and the toughness of the N9TAX has made it my choice. Also, N9TAX will cut an antenna for an exact frequency if you want them to. I also ordered two for GMRS. One at 462.550 MHz and one at 467.600 MHz. Both are spot on when it comes to to SWR and perform very well. These 70 cm antennas are great for use in CERT comms. Short, sweet, tough and they really increase your range. Add one to your CERT kit.

This one does out perform the N9TAX by about 20% based on the extra distance of contacts I can now communicate with. Saying this only proves to me the quality and ability of a $30 antenna , which is the N9TAX, a SOLID performer for a Great price !

    Josh, thanks for all you do here. My thoughts on test methodology: I would have liked to see a SWR sweep for each antenna for both bands with your RigExpert analyzer, then superimpose them using the AntScope2 desktop SW for comparison. The RF choke on the antenna may play a role in improving SWR. Next is getting the variation out of the test by using a tone generator of constant tone and volume instead of your voice to do the actual SNR measurement. Not sure how much it matters for FM, but SSB would matter. John

      I have had the opportunity to speak with Ed Fong via telephone on a couple of occasion, and I have found him a most helpful and knowledgeable individual. My most recent interaction with Ed was in connection with a custom VHF only J-Pole antenna cut to a commercial Rail Road frequency for the purpose of replacing 50 Ohm termination resistors found on at the end of two radiating antenna (Radiac) cables on the Manhattan Bridge in New York City.
      The J-Pole VHF antennas were engineered to bridge the physical gap between the ends of two Radiac Cables mounted on the Manhattan Bridge to improve VHF radio communications between trains and the Rail Control Center as trains crossed over the East River. Ed was most cooperative at meeting our specific non-Amateur radio requirements that helps to insure public safety.

    I have both the Ed Fong, and the Dual Band version of the N9TAX. In my own testing, they performed so similarly in practical use on both 2m and 70cm, It completely came down to form factor to me.
    My primary use for roll up are portable/emergency use antennas. I have a Condor "Side Kick" pouch for each of my portable radios. These contain APP 12V power leads, programming cable, Microphone, Signal Stick, BNC adapter, extra battery, etc. The Ed Fong rolls up and fits in one of these along with an extension cable. The N9TAX does not.
    So, the N9TAX is instead used as a backup antenna for at home, field day, etc where having a bulky antenna is not a problem.

    While I've been very happy with it, I may have to look at getting an Ed Fong for my pack and dedicate the N9TAX for a residency in my Jeep. I might make the change not because the Ed Fong performed slightly better in your tests, but because it is noticeably more compact (and presumably) lighter.

    My three favorite parts of this video: 1. The timing; 2. The fishing pole/j-pole mast; 3. The gear ties.
    THE TIMING-- For me, sitting on my urban back porch/fire escape with my favorite HT, a beer, a cigar, and my favorite net is ham radio at its best. Unfortunately, my HT can barely reach the repeater, so I end up going inside to use my base when it is my turn to transmit. I watched this video right after that net two weeks ago, and decided I want to try a roll-up j-pole before giving-in and rigging my base and its antenna to some ultra-portable configuration.
    Not an Ed Fong roll-up J-Pole to be found anywhere, as I write. So found his plans, and will build my own.
    THE FISHING POLE and the GEAR-TIES-- These provided the quick and easy set-up and tear-down I need for the antenna, and with any luck at all, will give me the ability to continue the porch-life with just my HT. If so, the whole rig can be slung over my shoulder in a small bag-- greatly expanding my out-door hamming options.
    Fishing-pole/mast just arrived and I am pleased with it. Had everything else for the roll-up j-pole. I have soldering to do this weekend. Wish me luck.

    I have the N9TAX with the short piece of coax, and its been a great antenna for a year or so that I have owned it. Last night I was working portable in the back yard, and incoming repeater signals were much lower than usual. I could not reach most of the Winlink gateways in the area, so I checked the SWR and it was above 5:1. Today I was going to perform a continuity test when all of a sudden the SO-230 connector fell off of the antenna. I suspect that was what caused the bad performance, but I'm not sure how it happened. I don't blame the antenna build because its a solidly made antenna. I've been using it quite often in various portable setups, so it must have something on my part.

    👍🏻 Thank you for the excellent comparison.
    Quick question for Josh and anyone else out there…
    I need a roll up style antenna for ONLY UHF (no VHF) .
    The frequency range is 462.xxxx through 469.xxxx and perhaps 453.xxxx/458.xxx, if it doesn’t affect the performance on the higher UHF freqs.
    These are for me to include in family member “EMComm” bags as external antennas for Motorola XPR7550e portables.
    If you’re familiar with that transceiver, you’ll wonder how the radio will connect to antenna.
    So, If I can’t manage to “hack”the antenna issue, I’ll be using Hytera PD982G. The FPP, encryption and other things actually make a much better pick.
    Thanks !

    I use the same Ed Fong jpole with an HT from my hotel room when traveling on biz. I figure out which way my window is facing and then use the RepeaterBook app on my phone to find repeaters in that direction. I also ask for rooms that are on higher floors. I also call out on 2m simplex, which is hit or miss, but often there's a highway in view and I can have short qso's with travelers also monitoring simplex. All I do is use a binder clip to hold the tip of the antenna to the curtain rod or a push pin that I stick in the wall above the window to dangle the antenna from. The antenna has exceeded all my expectations. I frequently talk to hams that are stunned at how well my signal is being received when they find out I'm using an HT and my location which, at times has been 20 miles to the repeater. I do try to mount it in the middle of the window, away from the metal frame around the window.

  • @rodsnitker

    Good Review! You mentioned the ferrite on the N9TAX - I assume the concern is prevention of common mode current. I think I remember in an interview with Ed Fong that he mentioned he uses a coax sleeve choke to prevent common mode current in his design, but I may be wrong.

    • @HamRadioCrashCourse
      @HamRadioCrashCourse  2 года назад +2

      It's just a different way to choke common mode. If you do the sleeve, that is just a bunch of beads with the coax going through. My preferred method is use a bigger ferrite with larger inner diameter and wrap the feedline to give it multiple passes.

  • @RossDaniel-san

  • @Woodborn
    @Woodborn Год назад

    Regarding the low SNR on UHF, I don't think that it's fair to blame the antennas ("it takes quite a dive"). The whole system as a whole is poor on UHF, not necessarily the antenna. It could simply be your HT that is not very good on UHF or your home receiving antenna for that matter. Ed Fong compared his antenna in UHF to a reference 1/4 mobile antenna, and its performance is virtually identical. I'd suggest to always use a "reference" antenna to compare to in further antenna tests. These quantitative tests are super great, keep them coming!

  • @keithsafford3056

    Just found this comparison. I have had the N9TAX antenna hanging off my porch for the last 4 years and have had 5/9 signal reports on my Yaesu FT-8900 when it was my base VHF/UHF station and now my FT-8800 is my base station and I get 5/9 reports (The FT-8900 is in an Armoloq manpack now) and I have the CR8900A with a ground spike to use portable and will probably order another N9TAX as a rollup. Never heard of Ed Fong antenna's until a couple of years ago (sorry Ed). Bottom line, if you have something, and it is working great, why change, i.e. if it aint broke, you are getting great signal reports, nothing to change.

    I'm not surprised by the 70cm results. Ed Fong explains in a RUclips video that he uses 1/4 wave stubs to make his antenna a true half wave radiator on both 2m and 70cm. My understanding of the N9TAX is that it works harmonically on 70cm and is not a true half wave radiator. Ed Fong explains in the aforementioned video that j-poles harmonically operating on 70cm are very lossy and his analysis shows they don't work much better than a duck antenna. That and size are why I bought the Ed Fong.

    I don't get what you're talking about at 9:00. The Ed Fong has better performance results, for 70cm where the N9TAX is lacking them, but you say that the N9TAX antenna is more of a 70cm antenna? Also, from what it looks like, different matching is done to dual band these antennas so they could perform differently. I don't know what the 70cm gain should be for the N9TAX, but it's supposed to be around 2dbi for the Ed Fong, so quite similar to 2m. The reduced signal is going to be at least somewhat attributed to transmission line loss, and possibility due to reduced gain over 2m. In any case, you can't compare these antennas at 70cm with the current data.

    • @HamRadioCrashCourse
      @HamRadioCrashCourse  2 года назад

      I didn’t say the N9TAX was better on 70cm I said it’s possible is performs better on 70cm. I will do another test specifically on 70cm to provide the details. At no point was I testing 70cm since we only had the Ed Fong data point (something I already had)

    • @Datzfunk
      @Datzfunk 2 года назад

      @@HamRadioCrashCourse I guess It's just confusing at that point because you say the N9TAX is cut a little bit more effectively for 70cm, and the Ed Fong takes a dive there, but we don't know the N9TAX numbers. It sounds like you're comparing the two and giving the upper hand to the N9TAX with no data.
      Anyway, I appreciate the test. I have an Ed Fong which seems to perform quite well, so it's interesting to see the 450ohm twin lead version with what appears to be different matching for dual banding.

    I think you should do that test again and use the bow set up that is recommended by n9TAX, and due to the design of the dual band antenna the folded dipole side will be affected , if either radiating side is damaged it will affect the others performance. If there is damage to 1 of the coaxial shunts which change the signal velocity and determine the shift in radiation points, you will get a result like you had in that test. And check out the mono band 220 from n9tax , tuned to 223.500,...the harmonics make it work with a low SWR on 2 m as well. And it's about half the size of that dual band.

    The N9TAX appears to be made of window line, not twinlead.
    Unless the antennas are mounted up and in the clear, (away from that huge tree-trunk,) and not hanging parallel to an antenna mast of uncharacterized composition, the SNR on a given band as opposed to on a different band cannot be adequately compared. All you can reasonably do is A-B comparisons of different antennas on the same band.

    • @pale_2111
      @pale_2111 2 года назад +5

      I did. I set up one for a ham in a nursing home. The feed point of the antenna where the coax connects to the window line needs to free hang. Having the feed point secured to a wall will increase the SWR.
      Some body put some tape around that area of the antenna to secure it to the wall. I checked the SWR on the antenna with my IC-705. Sure enough the SWR was higher than 3:1. I removed the tape and rechecked the SWR. It fell below a 1.5:1. Not sure there was a nail in that specific spot or what, but after the tape was removed and the feed point was free hanging, the SWR on the antenna dropped significantly. If he had used a FT70D I got him any longer, he would've burned up the finals in that radio.
