Yesterday made the antenna very broad band but tuned it to perfect 1:1. Thanks for sharing
Excellent!
Excellent video sir!
Great video Gil and nice Yagi, I bought one of those TechnoFix mics also for backup, it works very well on my 251A and I get good audio reports. I look forward to more videos with the IC-251E.
+Joel Caulkins Will do ;-)
It is Yagi OWA
Your vice was working as a heat sink should have done it off to the side
Dv7bkg extending my 73s and thank you for sharing
Great work Gil. I hope to work you on 2m SSB some time! I use mine portable only however!
Thanks for sharing the video!
73, John M0UKD.
Thank YOU for posting the design with the clothe-pins, great idea! I will use mine portable as well as soon as I can!
A good portable antenna. It's not a "Gil build" unless it has epoxy! Good work, nice project.
That's right ;-)
Will build this antenna with 2mm aluminium wire to see how it works. Want a more easy antenna in the field instead of a quad for 2m. Great video Gil. 73 Lars sm3uwz.
Great, let me know...
@@RadioPrepper will Do.
Great video Gil. I did a 5 element quad and got it working from Low section 144,300 up to the repeters on 2 meter takes a bit of a time but it works fine. Hope to work you on vhf on ssb some day. 73 de sm3uwz/Lars
Good work & super-antena.73 from Tenerife-Canary Islands EA8DGA
Thanks. I was there two weeks ago!
you are heating the whole bench vice. if you like it colder, just take a bigger one.
Am able to trigger the repeater on VHF but the voice is not very clear. Is there any adjustment in the reflector. Your reply would be highly useful in getting a few more repeaters without difficulty.
That I do not know sorry.
what are the ferrite type that you use ? how do you know this is working properly ? and out of curiosity, aren't all dipoles require a BALUN ?
I don't remember!
What are the specifications on the beads you used for the choke in box?
Unknown unfortunately, Ebay Saturday night special...
what do you use to support the antenna? how do you attach it to the support? usual u-bolt attachments seem too heavy for portable work
Hi. I use a fiberglass pole. Attached with a piece of masking tape.
I built this same version and worked amazingly on the lower half of the band 144.300ssb but it was resonating flat on 141mhz out of band according to my analyzer. Today i thought i was clever and wanted it to resonate alot higher around 145 to have ssb and fm band available with the lowest SWR, but things got really weird completely detuned yagi. Any advice to make this version more for 145.000mhz. best of both worlds which is always not possible. 73's Gil ZS1WE.

I think you would need to recalculate the elements... Or reduce them all by the same length little by little...
@@RadioPrepper Many thanks I have done so and finally got it to resonate where I wanted it too. 73 Gil
nice looking antenna-- but more explanation and the electro-syntho muzak detracts from the quality of the video. Had to mute it to avoid going crazy from the repeated techno chords. Grrr....
What metal did you use??
Hi, aluminum..
@@RadioPrepper can i use iron?
Sure, but not as good. Best is copper.
@@RadioPrepper Thank you, I made it with iron and it worked too .
The vice is acting as a heat sink
There is that, certainly..
You will have fun with 2 meter SSB =)
+Pat Hopkins I hope so. There aren't many users around here...
I had the same in my location for 220mhz SSB .... but found if I got on and worked it for a few weeks found several in the area that had the same equipment setup 8-) I have worked 1200 mile plus TROPO SSB 144.200 mhz contacts using a Big Wheel OMNI's at 35 feet AGL with 180 watts =)
+Pat Hopkins Nice. Well, I made one 20km SSB contact, but at least I know the radio works..!
You talk too much
