Antenna interferance

[robertson40]

I am wondering if antennas will interfere with each other if stacked on a single pole, if so what clearance between antennas should be maintained.

I'll be using 800mhz and VHF / UHF

For receiving? No.

What can happen is that if the antennas are too close to the support structure, or too close together on a horizontal plane, you can make them directional.

Thank you so much

I should add that if you are running a bunch of different receivers you can get some noise from the local oscillators in the different radios if the radios are too close, or if the radio has poor filtering, poor coax, etc.

Just wanted to add just make sure that your antennas are grounded very well.....

What's the best and cheapest coax cable for outdoor use ?

The best is not cheap. Beldening 9913 can cost up to $2 per foot. Your main concern is coax length and frequencies that you are trying to receive.
