Hello,

Very weak in ant theory's let me please ask:

Do receiving only, <30 MHz. Just your avg. Sr. sw listener.
Enjoy it very much.

Presently have a 35 foot simple long wire outside.
9:1 Balun at end, then coax run into house.

a. What freq. range would you expect this ant to be "best" for ?

b. Thinking of adding another 40 foot, or so, length to it.
Worth doing ?

c. And if a good idea, the "problem" is that it would have to
be at right angles to the present wire (in the same plane, though, ten feet above ground).

What implications would this right angle have ?

Thanks, as always,

Bob

Without an antenna analyzer it is just a guess as to what frequency your present antenna is "best" for.
Otherwise, try adding the additional wire and see how it works for you. Much of the fun with antennas
comes from experimenting. My experience with wire antennas run at a right angle has been ability to
hear additional stations not heard on previous one direction antenna.

Hi,

Thanks.

Project for next week is to increase the length of my (receive only) ant.
from 35 feet to about 70 feet.

Will be interesting to see the changes.

Regards,
Bob

Do it. You will end up with the length of the old Radio Shack short wave antenna they sold for 7 dollars. Those were the days. It was 50 feet plus 20 feet of lead in wire.

If you listen to any regional amateur stuff on 40m you will probably loose the 50 to a couple hundred mile NVIS propagation going to 70ft but very distant stations at all frequencies should improve.

Thanks Guys,
Working on it.

At my age now, seems like things take a lot longer.

Have a RSPdx; will be interesting to see the, hopefully, improvement in what i now have.

Thanks for thoughts,
Bob

I have run a 100' endfed "Lazy-L" receive antenna for years now. It runs from feedpoint north 45' then turns and runs 55' west. Mine is left-angled:) but I decided to make the bend a "soft" one-I bent it around an 8" round PVC. And like WA8ZTZ stated, the part of that wire that's broadside to the north/south gets me tons of beacons in Canada that I was deaf to before with just the east/west 45' I had before.
So yeah you'll see some benefit doing this.
