You can just about bet it will change when you go flat. Extra work (been
there) but worth it. Let us know how much vs 1.5:1 at the V stage. Would be
kinda interesting. Hope you get a bunch of dit-dahs this weekend. (You too

Subject: [OKDXA] Dipole Antenna Question
> Builders of wire antennas I have a question that likely could be answered
by a scan thru the pages of the ARRL handbook but I figure I can get a
quicker (possibly even wiser (wiser to mean intelligent vs. wise acre) with
a query here.

> I'm putting up 20 mtr and 40 mtr dipoles for alternate antennas and have
constructed them using the familiar 468/freq/2 per leg. I hoisted each on a
mast (approx. 35') and tied off the ends at a lesser height. They almost
resemble Vees. SWR is about 1.5:1 at my design freq. on each and my
question is:
>
> When I install them permanently I will get them to the dipole (horizontal)
position vs. a vee looking position. If I get them to a flat SWR in my test
position, Vee with a 35' center what should I expect the SWR to do? My
thinking is some of you have an answer that can let me trim/add while I'm
testing before I hoist them into operating positions.
