I checked with Portland Bolt before i sent the email , they have the material and are quite knowledgeable , however , they weren't too interested in such a small order of only 3 pieces since they had
Hi Jerry, Here are two mechanical designs for the 40 meter W6NL Moxon. Standard and heavy duty. The performance of the W6NL Moxon is very good. Good gain, good F/B and low VSWR across the entire band
Hi Jerry, Here are two mechanical designs for the 40 meter W6NL Moxon. Standard and heavy duty. A pair of two element W6NL Moxon's weighs about 100 lbs and the pair of four element Yagi's weigh a lit
I just recently received a pair of AS line isolator's. I had Jay + Bob modify one of the W1JR baluns.. and put 7-16 Dins on both sides of the large NON-conductive nema box. Inside, it consist of 4 x
I'm patting myself on the back now for finding TowerTalk and getting so many quick replies and good answers to my question. I thank you all. I must apologize to U.S. Towers. After posting my query an
Part looks good, but the "air core" 5 turns on the paint can is unlikely to be very effective. 73 Roger (K8RI) will give you 2083 ohms on 6m. If you use RG-393 coax, you can then stuff 5 kw CCS all d
A question to ask is whether you really need a vacuum variable at all. Unless the antenna is close to a half wave and fed from the end, the voltage at the feedpoint is pretty low, even running very h
Thank you for the suggestions. I called Advanced Testing in my area and got some information. First, I checked the trustworthiness of the concrete company. That checked out. The technical person I sp
That's an old wives' tale. There is VERY little dielectric loss in decent coax at 2 MHz. Heck -- I used 10 ft of Commscope 3227 to resonate a transformer at the high Z feed point of an 80M half wave
I found 40 seconds for one rotation real nice for contesting after I built my own rotator. I turned a christmas tree of 5 element yagis 20-10m + 3L FS on 40m without problems, but the stress on the d
concrete for a base? I can see all this if you have an gigantic hundreds of feet high superstation, but the average guy doesn't need to have his concrete analyzed. rebar/cage they say. You guy correc
I had some C-band positioner cable that had all the wires I needed for direction indication and a pair of #10 or #12 (R&B) wires to drive the motor along with two RG-6's all molded into the one cable
Gene, I didn't misread or overlook it at all. The function of an arrestor is to protect sensitive (and expensive) electronics from a strike. ALL IT DOES IS SHORT THE COAX. That remote switch is neith
OK.. I just discovered I have 2 x cracks on the flange portion of the bearing, that's on the end of the drum... the end that has the big chain drive on it. There is a bearing on each end of the drum.
type clamp.....and also a mating SS lag bolt and nylock..for the assy that goes around the boom. DX eng has them in only 2 boom sizes..2" and also 3" . I used the exact same boom truss assy years ago

Personally, I think it is highly unlikely that significant corrosion would travel down the path of a thin wire. It certainly isn't a moisture issue, since moisture readily penetrates concrete anyway.
I always free climb, then snap the belt when I get where I'm going. Been doing it for 20 years or more. There's just one rule -- hold on tight. But I'm 54 now, and suspect that in a few years I might
