Antenna install

Post by kfr439 »

I am getting ready to install 3 different antenna in my 1997 s-10 blazer. I was wondering if there was a space requirment as fas as how far apart the antennas have to be spaced. Thanks for the help in advance.

What bands do you intend to use? What kind of antennas? Where are you mounting them?

A safe bet is 1/4 wave all around each antenna. Mine are all UHF and spaced 17" apart (which would let me vary the antennas to different bands if I wanted). I've heard people say as long as you have a 6" radius that you're cool.

I have 2 spectras right now. A 800mhz and a vhf 136-174, but I am planning on getting a uhf one so I figured if I am going to install the other two antenna and I am planning on getting a third radio I might as well install all three antenna at once.

As KG6EAQ said, a quarter wave apart is good. keep in mind, that means a quarter wave at the lowest frequency. So if you have a UHF and 800, you should have a quarter wave of separation at the UHF frequency - at least six inches. In your case you have a high band VHF, so that antenna should be 19 inches from any other. Farther is always better anyway.

Good luck,
