Steve offers: "It boggles my mind why we risk confusion and even talk about "percent grades". Isn't that why virtually every high-school graduate took geometry so we would have a better way to descri
That's a huge loss. Those who know L.B. from his writings can infer the level of grace and elegance this man radiated in person. He was, for several years, a hugely popular speaker at many Hamfests,
Please note that Jack Stone was the one who wrote the news about L.B. in the first place, and the one who sent the Sheriff on his sad trip of discovery. Does the following message portray a money-gru
Wait a minute... We understand jam nuts. A jamnut prevents the pair of jammed nuts from moving WITH RESPECT TO THE BOLT or threaded rod; but they don't add any additional protection against the jamnu
L.B.Cebik would agree with this. His modelling of a center-fed inverted-L (basically a 1/2 wave inverted-vee rotated 45 degreees to put one leg in the vertical plane) showed insignificant improvement
"A while back we had a discussion on using lock nuts AKA jam nuts." That might be the source of our disconnects. We're equating "lock nuts" with "jamnuts". In my simple-mindedness, I think of a lock
Several (5 or 6) years go, I had an issue with erratic readings that would go crazy when commanding rotation, then revert to a strange angle at rest. After confirming flaky resistance readings on th
I've used this on 80M, fed with RG-8X and with a choke at the feedpoint, for several years. According to Cebik, it should work well on other bands, too, but you might want to use ladderline in that c
As far as I remember, the brake is on the motor shaft. When the DC motor is energized, the shaft moves axially, pulling the brake disk away from the fixed disk. As soon as the motor drive voltage is
Jack, for the past 10-12 years, our club has used a simple device for our 80M vee over a 20M quad for Field Day. We found a sealed automotive bearing whose O.D. was just right for slipping into the m
Bob, I bought mine as a C-4, which had the saddle for the 40M element already mounted, so I can't comment on installation. The location for the 40M element is shown on my drawing (# dwc4.003 - 1995)

Tom, Setting it up as a half-wave inverted-L and feeding at the center should work well. I am very happy with mine. If you only plan to use it on 80/75M, you can feed it with coax, but be sure to dec
It doesn't look like the stress number includes the winch or base assembly, which probably accounts for most of the difference. Chuck, N4NM Does anyone know the weight of a HY-Gain HG-52SS tower? Ju
Jamie, the impedance reading you are seeing now is (48.3 + j14.4); but your instructions want (46 + j12). So youre pretty close. The j term and X refer to the same thing (reactance). Impedance has t
I have some that's older than that; and it seems to be fine. No hard data, but no issues, either. I also use it for lubricating latches and strike plates on our exterior doors. Really slick; and I wi
