5 yds is the minimum buy from a mixer? Holy cow...here I can get 1 yard delivered if I want (for the cost of one yard), they schedule you for the end of the day when the mixer's going to go back almo
[Steve Katz] No, not lucky. RG8/U and RG213/U (.405" diameter, fairly lightweight) doesn't really require a strain relief loop, however a "drip loop" (to prevent water from running down the whole le
Jon, It does sound as though the rotor is binding in one direction. Make sure the load above the rotor is very balanced; any amount of imbalance when an AR-22 is used without a thrust bearing will ma
[Steve Katz] Peter, you are indeed lucky! When I used an AR-22 with just a single 2m long-boom Yagi back in the mid-1960's (at that time, it was a single 15L Telrex, 28' boom), the first windstorm s
Here's what I would do, based on what I've done in the past and what has (and also has not) worked: -It's probably a CUP, actually (conditional use, not temporary use). Check to be sure. If they're p
At HF, I doubt you'll see much savings going to 1/2" CATV hardline over Buryflex. On 10m, the difference in 195' of line is about 1 dB or so. On 40m, it's less. However, there's no reason not to use
[Steve Katz] I haven't been following the "tubing" thread, but aluminum only stays shiny if it's been treated with something to stop oxidation. I go to the local anodizing shop (they are everywhere)
Sure looks like an HD354 to me (Tri-Ex, and a lot older than the 1980's), or possibly the Tristao counterpart (also a lot older than 1980's). The welded cross bars, without any diagonal ("zig zag") s
4" dryer vent is my favorite. Cost, about $3. Keeps water out: Yes. Will pass any number of standard coaxial and rotor cables, from one to about 20: Yes. Builder already has hole saw that size to mak
You might contact Neil, K6SMF about this if you don't find an article anywhere. He runs a converted 204BA on 17 meters and it works exceptionally well. He used the whole boom length and changed all t
With such a large tower at my disposal, and evidently access to its top at least to attach the wires and transmission line, I'd probably do something else. wish to work, and the narrower the pattern,
You only need about 40 dB isolation running 1 kW output, as any receiver I've ever seen can handle 100mW (+20 dBm) directly into the antenna port. However, the B&W switches I've used in the past did
I'd replace the pointy-top section with a flat-top one and use a 2" thrust bearing. And also a 2" mast. Since you're in for thunderstorms and high winds, work done in such conditions will be perfect,
Best I've used lately is a vertical dipole installed as a sideways "vee" from a 140' tall tower. Dipole is full-sized (255') but pulled out away from the tower at its center using a guide rope, then
Hi Tom, I didn't look, but presume you're right, as I've heard of people using large masts with R25 "pointy top" sections. I just never saw one myself that would let a 2.00" OD mast rotate -- the one
[Steve Katz] Hi Blake, well, as I said, I never saw one that would let a 2" mast rotate, either, and I've used a lot of R25's over the years. But then, I don't have a recent Rohn catalog! -WB2WIK/6
