Well it does work. Did not say it is matched but the height of the mast (on a sail boat) & the clearance makes up for a lot of the "short of technical correctness". The normal coaxial switch has a shorted port for the non selected & it is not going to allow you to dump RF into the TV. But you would not want to double select the selection before you try & transmit on the VHF. I have shown many of my sailing mates & some of them use the top mast ant. for TV when local sailing with their spare rail mounted VHF connected to radio
. I do have the radio
selected to the low power
(1 Watt) pos.to allow for any failure to check. The field strength meter that is provided with the TV menu will show how good the signal is & all that is required is a PL259 joiner & a fly lead to the TV to test the setup before spending the $30 on a cheap
ham type of coax switch good to 600 mhz. Use RG58 52 ohm all the way from the joiner & enjoy the mismatch!!
