Absolutely; he should buy it! And he should go to RFI Service's training seminar, too. For some customer feedback on both, contact Mike Gruber at ARRL HQ. Please QSP this to Tower Talk as I am not on

Tim: I suspect that the beads you used are the 1" long ones that have a large enough diameter to fit over RG-8. As you point out the ferrite in the bead is important. I used to make choke baluns usin

I think this topic is sort of under the 'towertalk topic umbrella'. This is a very interesting article on propagation. Adcock's article on "Propagation of Long Radio Waves" at http://www.lwca.org/lib

Just relax and feed the power to the system. Use a tuner to adjust the impedance at the station for the 40-2CD when you use SSB. If the 2.5:1 bothers you at (21.000 you said, but I suspect you meant

The resistive part of the impedance of the dipole is a function of its height above ground. The ARRL Antenna Book and Handbook cover this. The center of your antenna is significantly lower than 1/2 w

This procedure is used by more than one 'institution'. It tends to assure that the problem is both real and significant. (I am not supporting this only commenting on it). If you are making a BPL com

A very quick calculation which takes the weight of the Force 12 antenna at the end of a 72 foot arm should indicate that there is a very large bending moment when the top is near the ground. The for

It is my opinion (and only that) that the wall thickness of the tubes used by Heights in 1972 (when the tower was fabricated) was insufficient for the stress I placed on the tower sections. I believ
