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.

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! 73, Charlie -----Original Message----- From: Topband [mailto:[email protected]] On Behalf Of Jim F.

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 ? 73 Jim / W1FMR / QRP _________________ Topband Reflector _________________ Topband Reflector
