Axel Mishael Posted September 27 Report Share Posted September 27 Hi, Do any of you work with two (or even more) BST 75-216 Transmitters? do you use the same antenna for both? (let's say the sna600 with the miracle whip) or do you use antenna for every transmitter? Thank you, Axel. Quote Link to comment Share on other sites More sharing options...
Rick Reineke Posted September 28 Report Share Posted September 28 For optimal performance the antennas should be a specific length. As I recall a 5/8 wave wire antenna for a 216 mHz Tx is around 14 inches. 72 mHz would be longer. There are formulas to calculate antennas lengths.

Axel Mishael Posted September 28 Author Report Share Posted September 28 My question really is if I can use two transmitter (two different channels) in the 216mhz spectrum and both share the same antenna. Quote Link to comment Share on other sites More sharing options...
Johnny Karlsson Posted September 28 Report Share Posted September 28 I have read that it’s ok to do with a proper antenna combiner. Personally, I prefer to keep transmitting antennas separated and on different height planes. Probably just voodoo superstition in my part… Quote Link to comment Share on other sites More sharing options...
Jim Rillie Posted September 29 Report Share Posted September 29 Not voodoo, Johnny. Just physics. Somehow a combiner works to allow this, but I still believe separate transmitting antennas distanced properly will give better results. just my 2 non-existent Canadian cents Quote Link to comment Share on other sites More sharing options...
