[OKDXA] Dipole Antenna Question

[kd5gho]

I can tell you unless you trim your dipole when it is in its final resting
place, the swr will change.
+or- their is no telling.
The hight above ground and its prox to other structure will effecr swr.
If you use ballanced feed, be sure to avoid 1/4 and 1/8 wave lingth of your
rez freq.
Just put er up and hope you dont have to add wire.
Hope this helps.

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.
