Multi band Yagis on same cross boom
I just installed a 1296 Mhz loop yagi in between my cir Pol 70 cm and 2m satellite antennas. It is a 10’ + fiberglass boom. Will the 1296 antenna cause any problem with the other two yagis?

Rick,
There is always some interaction between antennas.
But a 1296 yagi with a fiberglass boom will probably be unnoticeable.
Good luck. Which satellite uses a 1296 MHz uplink?

I have a similar configuration and it does not cause any issues that I am aware of.

Here's a great article that we use for configuring our stacks for the VHF contests.

I have a 1296 loop yagi mounted a few feet away from my 435 cp yagi. I used the 1296 antenna to run the feed from the 435 antenna. I used a piece of tubing to join the 2 and ran the feed back from the 435 antenna and forward on the looper. Mike
