    Yesterday made the antenna very broad band but tuned it to perfect 1:1. Thanks for sharing

    Great work Gil. I hope to work you on 2m SSB some time! I use mine portable only however!

    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.

    A good portable antenna. It's not a "Gil build" unless it has epoxy! Good work, nice project.

    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

    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.

    you are heating the whole bench vice. if you like it colder, just take a bigger one.

    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....

    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.

    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 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...

    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
