Hello.... I recently put a new rf choke on my 204ba ( 12 turns, 11 inch diameter as per the hy gain manual) and 135 feet of 1/2 inch hardline. Swr is good, directivity is fine. Problem....the 204ba a
First of all, thank you to the many responses. My hy-gain manual for the 204ba has an error. According to the manual that I have, the RF choke is 12 turns on 11inch diameter....definitely should be o
Thanks to everyone for their input...Consensus is just conditions. I plan to replace the improperly wound rf choke with a good quality current balun for a beam? ....only run about 1200 watts at most.

I made use of the Cushcraft contact, John David. I even had a direct line to him and ordered parts through him. Unfortunately my timing was poor. Before I could receive the parts, as everyone noted,
After searching for many years for a source of CATV cable, the Gods must have been shining on me today. The local cable company had run a 300ft piece of line temporarily until they founf the problem.
To the many folk who responded, a much greatful thank you. Since every situation is different and I have been known to do things first and then try to put a square peg in a round hole afterwards, all
I am the proud recipent of numerous rolls of 75 ohm, 1/2 in CATV cable. Since all of my antennas require 250ft or mor runs this is a real blessing. I have a few questions before I start replacing the
Thank you to everyone who responded....I will just use multiples of a 1/2 wave section. I will assume the velocity factor to be .84 since I can't get any real answer from the CATV company. I needed a
A while back I bought several male-female 8 conductor assemblys for use as quick disconnects for rotors. I seem to recall that they were used in the automotive industry. They have molex plugs and abo
I am in need of 4 marine grade pulleys for wire antennas. My rope is 1/4inch good quality stuff that I had bought from one of the usual suppliers. What type of pulleys do I need and where is the best
Many thanks to all who responded. I now have direction in my quest. It would be wonderful if I could get a great deal on HD rotor cable, but it looks like I will have to bite the bullet and pay $.75/

I am going to install an 80m delta loop with the apex at 90feet. 1. Is that too high? 2. I know that a 75 ohm 1/4 wavelength transformer is used at 1/4 wavelength down from the top for vertical polar
Thank you to everyone who responded. I am hoping to get it up this weekend. From the responses, I will feed it about 64 feet from the top with 50 ohm coax. The legs will be 95 feet each. Again....m
Help, I lost my antenna handbook. Does anyone know the formula that is fairly accurate for a 75ohm quarter wave tranformer for my 80m quad. is it 234xVF or 246 x VF
I have been using 8-pin molex type trailer cables. Both the male and female come with #12 or #14 gauge stranded pigtails, about 3 feet long. They work great/ I got them from wiringproducts.com Carol
Hello, I have an inverted vee up about 100 feet. It resonates at 3615. From past experience, how much should I add to each leg to get it down to 3515? Thanks, Carol __________________________________
