Separate antennas for separate bands

Paul F6EXV

Hi all
I have a Flex 6500. I have my multiband HF beam connected as antenna2, and my 6m beam connected as antenna1.
I cannot monitor let's say 30m on antenna 2 and 6m on antenna 1 at the same time. As soon as I switch one band, the other panadapter also switches antenna.
I do not think this is normal behaviour... How can I fix that please ?

The most common configuration would be a tri-band or multi band antenna, or a log periodic, anything that can do multiple bands(but is not frequency agile like a SteppIR). So let’s say you have a 3 band yagi, you can listen to all 3 bands at the same time

Paul, I am not sure about totally useless, but in that configuration you would have to do some switching magic to say listen on 80 or 160 while you were on your ultrabeam.  for instance you could switch the 80 vert to RXA while operating on the upper bands through 40, and reverse them when you want to operate 80.  But I do understand your concern.. and the best flex radio for that configuration are the following models: 6600, 6600-M, 6700.  all 3 have dual TX/RX antenna capability and 2 SCU's.  Single SCU units that behave as yours does are the 6300,6500,6400, and 6400-M.

Paul,

Yes...you will need a radio with an additional SCU with your current set-up.  The 6500 is hardly useless and you have 4 slices which can 'look at" a single antenna. (possibly 4 bands at once!) The radio can't be blamed when you have migrated to a more complex antenna (Nice!) set-up.

Best of luck...

Ah that makes senses.  Nice to be able to upgrade antennas!

Paul, your TRX has only 1 PTT output. That answer your question. So you need a Y-cable for PTT and then 2 ways: 1. you always switch one of your PA in standby or 2. you add a switch in this Y-cable and select manually then what PA you will using.
