wish to combine VHF rf tx signals into one antenna

[Nan and Sandy Sanders]

You can combine by band. 1 6M, 1 2M and 1 70CM radio into your triple 
band antenna. Other radios can be connected to other antennas 1 per 
band. However......... as a practical matter you will only be able to 
use one radio per band at a time because while you are transmitting 
any radios receiving on the same band will be desensitized and will 
hear only very strong signals if any signal at all. If you are at 
Tacos Sat we can discuss this a bit more.
