Hi Pier

- Try getting a portable SWR & walking around your lot, putting it to a " Blank
" frequency and checking where you hear noise, and where you don't

You should also check to see swhere on your lot you pick up 20 - 70 meter
frequencies your interested in

Try this both in the daytime, and at night..
THEN
You'll be able to put an antenna in the ": Noise Free areas"

Hi there, I am trying to build a longwire antenna for use in the 20 meter
band to 70 meter band area. I was looking for advice on what materials to
use for the antenna and the lead in lines. I will hook it up to a Drake r8B
radio. What is the minimum height it has to be? Where to ground it?.
Actually, does it have to be grounded if the radio is grounded at the
outlet?

I am a little limited in space as my yard is only 75 feet long and there are
power lines at the front. I assume that they are the source of an irritating
hum on the receiver on certain frequencies.

Thanks for the help in advance.
