I am looking to increase my reception to my South(see attached map). My radio, Kenwook TK-790, is in Cedar Rapids. I can receive mobiles with-in circle, the base radio at Brooklyn(40 miles) and West Liberty(35 miles) I can receive, with Brooklyn coming in better. The base radio in Iowa City is hit and miss(must shorter tower). I have used a RS 20-176, traintenna, and a homemade folded dipole. All three have basically had equal performance. All frequencies monitored are VHF-Hi(160-162MHz). I can only mount antennas in the attic. My coax run is apx. 20-28' of RG8. Any ideas?
TIA,
