You will loose a lot of distance with VHF by mounting it low. Our AIS receiver which currently shares the AM/FM antenna on the main mast. The AM/FM antenna on SM #387 is identical to the VHF antenna. I used a BNC "T" to split the antenna wire for the radio and the AIS receiver. I have noticed no problems with either the radio or the AIS receiver. This will not work for a AIS transponder, but, I am considering buying a small antenna for the radio, placing it inside the radio drawer. This will leave the AM/FM antenna exclusively for the AIS transponder. On SM #387, the triadic stay is rigged with insulators and the coax cable from the stay terminates in a coil behind the radio/Hydra drawer. I think it is too long for proper VHF (300mhtz = 1.6 feet of antenna for one-half of the signal's total wavelength), but possibly could be used to receive AM/FM, freeing up the Main Mast AM/FM antenna for your transponder. Let me know what you do. Best, Bill s/v BeBe, SM2k, #387 currently Malaysia
