Subject: Re: [WISPA] FM Radio interference 


I have been putting wireless on FM towers for some time now. 


If you do not do the liquid tight or the fiber, then the best bet is to use the 
Superior Essex BBDGE cable and ground the cable every 25-50 feet and it will 
bleed out the interference. 


It is a lot of grounding but it works.

I have an existing tower that has a FM transmitter on it. I believe they are 
just under 10,000 Watts. 
Since we have been one that tower, I could never link up Ethernet that runs up 
the tower to the equipment on the bottom at 100BT. I've tried ferrite rings on 
both ends, all cables are shielded and grounded. Always had to go to 10BT to 
get a link. 

I moved our radios 35 feet away from the bottom their antennas and still cannot 
link at 100BT. 

The new radios require 1000BT too use them to full advantage. Ideas? 

I'm considering conduit all the way up the tower. I don't want to put switches 
at the top.
