PeterI can't find for sale anywhere a 1:4 <a href="https://mastodon.radio/tags/balun" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#balun</a> for HF. It is for a low height 40m inverted V <a href="https://mastodon.radio/tags/NVIS" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#NVIS</a> <a href="https://mastodon.radio/tags/antenna" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#antenna</a>. Military versions such as <a href="https://mastodon.radio/tags/AS" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#AS</a>-2259 use the custom coax support pole as an impedance transformer.To be clear, I mean 12.5 ohm balanced antenna side to 50 ohm unbalanced coax side. The ones for sale on eBay/Amazon seem to be mislabeled 4:1 ones.Making one isn't an option: my hands don't work properly.Anyone any ideas.

Chris / KD8LCIAntennas have always been a weak point of mine. After a decade away from the hobby, and downsizing from a house to a ground level duplex I'm trying to figure out what the hell I'm going to do for an antenna. I've got my rig picked out (FT 991a) but wondering if I take the compromise and do something like their ATAS-120A and slapping that sucker on a tripod in the backyard when I want to play.Looking for opinions / advice. <a href="https://mastodon.hams.social/tags/hamradio" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#hamradio</a> <a href="https://mastodon.hams.social/tags/antenna" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#antenna</a>

RichardThis is a shorting bar that grounds utility 240VAC aerial cables to the ground. Spare operator required per use.It also acts as an adjustable, rotary V dipole, based on two alix telescopic verticals.It should be extensible, but we never used it beyond 10m so far.

Wes AFØAJAs planned, I spent part of my day today home brewing a new VHF/UHF base station antenna. It was an easy project, and initial testing suggests it works great. I wrote-up a complete description of the project, along with several photos.
