Our repeater antenna is located on a 180 foot water tower. We have not had a problem in the 4 years it has been up there. It is used for Skywarn nets when we have bad weather in the county. The past

There is some info here on static dissipation for repeaters. http://www.repeater-builder.com/rbtip/ You'll have to dig for it. They also have a mailing list you may want to sign up for. 73 Jim W7RY _

If you have not had a problem in 4 years and now you do you may look into other electrical hardware on the tower. It may me lighting systems that have started to arc when there is heavy rain or some

When we inspected the system yesterday, we noticed none of the antennas were properly grounded to the tower where they clamped onto the upright of the railing around the top of the tower. The railing

No. The nois is bad when someone wants to use the repeater. Mobile stations as so noisy they are hard to understand. One of the NCS usually has full quieting at 25W had to go to 75W to be understood.

This is just plain old precipitation static - we experience that probably 50 times a year. Exactly as you describe. Tom covers the subject very well in his site: http://www.w8ji.com/pecipitation_stat

I was wondering if this might be desense. If you are losing grounds this would change the impedance and how well the cans were working. 73 Roger (K8RI) _______________________________________________
