    A 102" (stainless mobile) whip is actually not quite at resonance at 11 meters. Adding a 6" spring, making 108" total, is. You should match better up in 10. At least that's what I found when I attached a 102" whip on the rain gutter of my folks' house as my first base antenna in 1974. You are bringing back what I loved about the radio hobby back then. Your wife sounds like a sweetheart, too. 73 de n9nbl

    Well executed test! FYI, an "S" unit is not equal to one decibel. The "standard" for an "S" unit is 6 db. Doubling output power increases signal strength by 3 db (only 1/2 of an S unit if all is in compliance with the 'official' standards!). So, quadrupling transmitter output power increases signal strength by 6 db, or only one S unit if the radios comply with the official standards!
    Unfortunately, few radios are calibrated to the "1 S unit = 6 db" standard. Moreover, the S-meter response in most radios is non-linear. For example, the meter may respond by 1 "S" unit per 4 db from S-1 to S-4, then 1 S unit per 4.7 db from S-4 to S-6, then 1 S unit per 6 db from S-6 to S-9, etc.
    A decibel is a comparative unit that is meaningless unless applied against either a constant or another signal. The usual reference above 30 MHz is signal strength compared to strength of a 1 milliwatt signal. This is expressed as "dbM." At frequencies above 30 MHz, "S9" is defined as a voltage of 5 microvolts (μV) over 50 ohms (Ω) at the receiver antenna connector.
    At CB frequencies, which are below 30 MHz, "S9" is defined as a voltage of 50 μV over 50 Ω at the receiver antenna connector.
    This standard is for an unmodulated carrier signal ("dead key").
    Your experiment was well done. A point to remember in the future is that the "S" meter readings you reported were not, as stated in the video, "db."
    We don't know if the two radios' S meters are linear; nor do we know whether they are calibrated for reading of S-9 for a 50 microvolt signal across 50 ohms at the receiver antenna terminals.
    Nonetheless, because the equipment, output powers and linear distance were identical for each base station antenna measurement, the experiment probably produced valid results, except at the 7 mile point where there was something interfering. Additionally, all three of the 102" measurements could also have been significantly affected by the rain droplets which absorb RF energy. The amount of absorption at 27 MHz CB frequencies is relatively small, however.
    Nicely done.

    • @ericdee6802
      @ericdee6802 2 года назад +1

      The Tram is made from fiberglass except for the radiating element. The Tram is a "Capacitave loaded half wave end fed antenna", Within the Trams fiberglass body, will be three different capacitors which are made from copper circuit board and are measuring within the "Picofarad" (puff) range. There are two capacitors at the base connecting the two opposing loading coils, then there will be a third "Coupling capacitor" connecting the base of the radiator to the final length "Top" radiating element.
      There are two basic reasons these antennas are fiberglass, One to make a EFHW (end fed halfwave dipole) polarized in the vertical position, the "Dipole" needs a supporting structure, reason #2 The fiberglass keeps spuradic radiation from coupling to the antennas radiator.
      If you loased the 102" steel whip with capacitance and have an inductive load on either the base, center or top, it will perform just like the Tram.

    Great test video, John! I like Tram mobile antennas, and am using a 3500 in the truck right now. I had a little too much fire in the wire for the antenna I was using, as the coax was too small to handle it. The Tram 3500 coax is holding up well so far. Your 1498 base antenna is definitely a keeper! By the way, the President Washington is back home with me now, and I let my father in law use the Galaxy base for a while. :)

    That was a well conducted test. Clear winner the Tram. The highest gain omni base antennas are known as the .64 wave. The vertical element is about 22 feet long. If you switched both those radios over to SSB, you would come in much clearer on the fringe. SSB has better signal to noise ratio since the bandwidth is half as wide as the the AM signal, plus you get about triple the wattage! I'd love to see an AM vs SSB test at those same checkpoints on the Tram.

    You sold me on putting my 102” whip up for CB. I own it just need to make some ground radials and mount it. Getting a tram means spending money.

      I typically use Belden 9913f and dx engineering 400 max coax. You can use any 50 ohm coax you like but, I stay away from rg58u small diameter coax and use the larger .405" base type coax since it has lower loss in dB and can handle higher wattage. Right now, I use 9913f for all my short patch cables between my radios and accessories since it's flexible, easy to bend around. From my radio room out to the antennas, I use the dx engineering 400 max coax which is a bit more rigid and is direct burial coax. I have it buried 24" in a trench from my house out to the antenna site. Burying my coax has helped lower the interference noise levels quite substantially from an s7-9 signal down to an s1-3 noise level because it's not picking up powerline, cable and other utility interference due to not being exposed to the air, it's all buried in the ground.

      Hi Mower Junkie, I am excited and lucky to own the NIB (New In Box) Super Star GR and a President Grant export model radios. These are basically 120 channel radios from the factory, 1-40 in the normal mid band position 41-80 in the High channel position and fourty channels below chanel one in the Low position. The reason these radios are so perfect is there are not many antennas that will handle a wide band width that is much broader that 120 channels. Also these radios will all work in the FM mode in addition to AM and SSB. I highly recomend these export radios that will work in the FM Mode. It is the same as changing your car stereo from FM to AM. As we all know am is noisy and FM is real clean (if you are fortunite to get to talk to another CB'er that has FM capabilities you will appreciate it). It is like talking and listening on Ham or a Govt (like PD or FD) radio just super clean audio. I like the possibility of these radios being able to be used locally for emergency prepairdness. I forgot I also have a President Bill Export CB 80 CH CB/FM radio (about the size of a 25 count pack of Marlboro cigaretts) You can Google the President Bill CB's, both CB(AM) and FM. Also you state you are using a Big Momma from the 70's. That is a good choice (they do not make that quality any more). I also have some older antennas that are still in use like the Lafayette Rangemaster ll. The Bill model is not much bigger than a pack of cigaretts. I hope to one day bump into you. 73 Cliff

      I used a mirror mount bracket. Make sure You have at least 2 ground radials, more is better, but 2 is the minimum. Good luck with Your antenna. Thanks for watching.

      @@MowerJunkie guess I’ll be doin some research into ground radials it’ll be ontop of a 3 story apartment building so that should help me get out just trying to choose coax is it bad to have extra coax? I don’t know how to properly install a pl259 connector so I’m trying to buy it as close to the length I need

    Two different channels, two different results. Changing channels invalidates the test as the SWR will be different.

      I had to change channels for the 2nd half of the test. when We went to do the test, channel 35 was in use. Both antennas are tuned very well, and have no difference in SWR on those channels. Thanks for watching, 73's from 151 SC.
