Your brain?

Here is how I grounded my tower and push up masts. About every 5 years I have refreshed the grounds on the masts by taking it all apart then cleaning and re-greasing. This year I used 'cold galvanizing compound' aka spray on zinc since I had a lot of rust forming...

I have a lifetime of experience with this stuff at work and home. Follow the NEC250, follow what the commercial cable and radio people do with tower grounding so when that electrical storm comes everything that you care about is tied to the ground system and that will keep everything at the...

This is what I do for my tower and masts. http://trolinger.com/david/ame25/tower.html

My first thought was to fish a plumbing vent pipe but you said no roof access. Mobile and/or remote from the workplace or another location.

For the original question about interference I would say try it and find out. I prefer monoband antennas, alone, on each tower or mast.

Don't know about your soil but I have always been able to dig in a few days. Just go a little at a time. Next; You want a "short load" concrete delivery company. This is a smaller truck that can go places those huge mixers cannot access. Don't use bags and a mixer IME(in my experience) way...

DMR is a black hole to me, no idea why we need that in ham radio but I think if you want to give it a try, go ahead. It is just money.

I retired and learned that the work NO actually works.

We just put down this beautiful dog after about 10 years of running and good times followed by 2 years of 'retirement' at our puppy palace. He was present at every antenna build that I did the past 12 years right up to the satellite system this fall. After a couple year break; He is able to...

There is all kinds of stuff to be heard. Check out Skip's book, now free to read. http://www.naswa.net/images/Radio_Monitoring_A_How_To_Guide.pdf

The answer to a glut of radios is obvious. More antennas.

I went through a lot of grief with solar charge controllers. Those solar panels make great RFI broadcast antennas. Long story short Renogy had an RFI-Free solar charge controller that solved my problems.

Thanks. Yeah the Google surveillance car was monitoring me closely that week. I was replacing the choke balun on the 40 meter antenna. While up on the tower I saw the google car driving the streets around me so I had a heads up. The next day I saw them driving towards me while I was on the...
