I am considering using this for a feed line to a rx only dipole made from 2 
hamsticks. My understanding is the losses in the feed line and the shortened 
elements, will not reduce the signal below the rig/noise floor. So I will be 
able to hear stations that I can't now hear (under my S-9 niose) using my 
vertical tx antenna. Yes, no, maybe?
