And, since energy can be neither created nor destroyed, all the energy that goes into destroying poorly chosen chokes or radiated down the feedline is energy that is NOT being radiated by the antenna
I guess the moral is, if you think disconnection is a guarantee, you're wrong. Unless you can anticipate every path and diligently disconnect everything every time. Of course, you can't ignore the po
It's not just the ones marked 100w that are cheaply made. And you can always do better yourself for less money than the good ones. 73, Kelly ve4xt Sent from my iPhone ________________________________
Wouldn't holding the coax with a sling-type grip in such a way that the bend itself is a tension-free loop, solve both problems? The issue in both cases is the unsupported weight of the coax pulling
i would disagree: the dBi numbers seem in line with other trapless 2-el designs, such as the C3 or XR3. Theyd be way high if they were quoted as dBd numbers, but take off the, what, 2.4 dB, to get to
I believe the tribander used at WRTC was a touch different than the Navassa5. I think WRTC stocked up when Cycle 24 was still supplying the TX 38, or when DX Engineering was supplying it. The JK Trib
Hi All, Is this true? A chap is advertising a 15-Meter Moxon on QTH.com <http://qth.com/>. Now, I dont want the antenna, dont like the antenna and dont need anyone to tell me not to buy it. Because I
Don't blow a section if you can't find stubs. Find a local steel supplier and have him cut you some channel iron. He can probably also drill holes for the bolts. Have him drill a third hole towards t
Hi Pete, The Steppir site is a bit confusing, but if you click on the "order yours now" and not the pic and not '...or click here' you do get to a typical Steppir order page. IIRC, $389. 73, kelly ve
Im pretty sure the 20-foot utility poles in many neighborhoods are not 80 feet long. (Three feet down for every one foot up would be 60 feet buried and 20 feet in the air.) I could see 20/3 (6.66 fee
I hope to pour in August, but I too have water. If it's only a few inches, is it worth worrying about? 73, Kelly ve4xt Sent from my iPhone _______________________________________________ ____________
Sounds as though the real beauty of the Metcal for PL259 work is that touching the tip to the shell sinks off enough heat the tip falls below its Curie point, which means the tip continues to generat
Anyone have any advice for getting the fishing line to come back to ground zero? I have no problem getting the line over a nice, tall branch but the arrow and tennis ball get caught up on the way bac
Thanks to all who replied. I used an amalgam of replies and hit pay dirt on the first try: teardrop lead weight, fired by a slingshot that had been a tennis ball-based launcher that, frankly, sucked.
I think porcupines fall into that category of 'if you tell a lie frequently enough, eventually you believe it, too.' Which might explain a lot of the opposition to Ufer grounds... 73, Kelly, ve4xt Se
Hi Deni, I have an MA8040V, which probably isn't as top-heavy as the R8, and I'd heartily recommend guying. There's a lot of movement otherwise, and that fibreglass tube at the base gets chewed throu
Trees or not, I think Id be leery of using a T2X for a DB-36. The DB-36 is not a small nor light antenna, 160 pounds and a 26-foot turning radius equates to 4,160 foot-pounds on the rotator, about 1,
I get the complaint regarding schematics. Even Ameritron gives you a schematic. That said, I've never called and asked for one. Maybe on request??? That aside, DX Engineering has been superb on servi
Based on a design I found online, and reverse-engineering for some omitted dimensions, it appears you would need the corners of the hex to be 21 feet out from the mast. Since they gain strength from
No arguing with results, however, I would point out that your 400 mile radius will mean quite a different QSO count in a high-density amateur region such as W1 than in other areas. A 400-mile radius
