Ok I have read your other posts so I know that you like to go after those hard to get signals. You know about the XG91 and you know how to find VHF long distance antennas. For maximum signal transfer and shielding from unwanted interference , RG-11 quad shield coax , grounded using a coax ground block connected to a good ground. And one of these ultra low noise amplifiers mounted close to the antenna.
