Dear Group: I just joined Tower Talk -- I've read through the last 5 years of archives and have certainly learned a lot I did not know. What a resource! I have a question: I have just ordered a US To

Dear Group: I am now ready to connect the tower grounding rod network to the shack grounding system. The crank-up tower is about 30 feet from the shack. Is it preferable to run the ground connection

I can't exactly remember, but I think the main difference in RG-213 and RG-8 is that one has definite MIL standards and the other (RG-8 I think) had more-or-less standards, but varied by manufacturer

Dear Group, I don't think I've ever seen any information on how a tower effects an HF beam's tuning and pattern. I've never simulated the effect or made any measurements myself. Can anyone tell me wh

Kent, it's sometimes suggested that you point the beam in a direction that will result in the least wind resistance. If your elements are longer than the boom, for example, you would point the beam 9

Yes, I guess it depends. If you have very small elements and a long boom, that would certainly make sense. With large HF arrays, I guess I would try to orient the antenna to lesson torquing around. A

Labor costs seem to be very reasonable here. I was also able to get a discounted rate on the rebar from a friend's company. I'm glad it worked out to something that wouldn't break me. Norm KE0ZT Must
