Thank you Charlie,
In that case I may be able to get another raised radial up before the action
begins
later this afternoon.
A receiving antenna is a definite possibility also especially if one could be
rigged to go up and down easily. Good idea.
Thanks again Charlie.

Hi, Jim
In my experience, the answer is "no" to both questions - although a full
size inverted L , while being a very effective transmit antenna can be a
really noisy receive antenna. Can you go out in the woods and hang a flag,
pennant or KAZ terminated loop for a receive antenna? Helped me a LOT o RX!
Good luck!

Charlie

Subject: Topband: Raised radial question from NH
Nothing heard this morning in NH at 1530Z.
Am in a condo environment where invisibility is a factor.
Antenna is an Inverted L fed through a series capacitor with two #22
ga. raised radials 136' long ~ 10 feet high running through the woods
which have stayed up 2 days so far.
One question :
Do you think that thin radials could cause an increase in receiver noise ?
Another question :
The 50 ohm feedline line is 25' long connected directly to the rig.
Is isolation needed to preserve the effectiveness of raised radials ?
If so, what would the isolation consist of ?
