I was lucky enough to get several sections of Rohn 25, and included was a homemade Hazer. I have never seen Hazer up close, but from the pictures of the Glen Martin Hazers, that look like they are bo

Is there a source of 3 inch material i can use for my old Kirk Delta Loop that is reasonable? I think I can use 2 6 foot sections, since the boom/mast clamp looks like it would easily splice 2 sectio

I am planning on putting up 60 ft of 25. I would like to tilt the base over on rare occasions. Is it best to just buy a hing plate designed for this, or maybe the 3 ft sections that can tilt? I usual

I have been thinking about putting up a Rohn25 with a homemade steel welded Hazer. From what I have read, if you do not want to do any climbing with the Hazer above you, the tower will be temporarily

When I lived in FL I had a Hygain 204BA at the same height as a TH3 (the 3 el beam) and I could barely ever tell any difference on RX. The TH3 has less bandwidth than the TH6 or TH7, but is only a li

I am wondering if my problem with the yagi is that I am using an old driven element clamp that came from an old hy gain beam. Could the capacitance from the driven element clamp (grounded) to the dri

I ended up changing the director to a reflector and the antenna resonatews fine now. I am not sure why a de-dir would not work. Doug N4IJ _______________________________________________ _____________

The rotor has always been sluggish but has gotten worse, maybe due to colder weather. I guess I will do as one of you said and put a small series xfmr to boost the voltage. That would be easier than
