VHF Antenna Mounting: Masthead vs Stern Rail
I'm faced with a decision that must be made before I bring my boat to mooring. I currently have my vhf antenna mounted on the stern rail. I want to mount it on the masthead (25' high from the deck) to increase my range. I have enough coaxial cable to run to the mast, however, it is type RG-58 and inadequate for a 30'-35' run as I understand. My question is a matter of compromise and opinion as to what is the most beneficial trade off given my scenario.
Should I leave my antenna where it is on the stern rail (3'/4' above water level) and sacrifice some range ? Or should I mount it on the mast head, gaining range, but suffering some dB loss ? As I am not well informed on the extremity of each trade off, I'm turning to you. Thanks in advance, I'm always grateful to have a resource like sailnet and its members.
