Hi Danny,
THanks for the description. I just wanted to be sure that would be all I needed to do and there was nothing special etc. I have not used this type of configuration and have only used antennas with coax lines connecting from the rig to the antenna. Sorry it also has been a while since I have done anything with antennas etc., so I am a little ignorent these days. I need to brush up on a lot of stuff I suspect. grin
