Recent production Yaesu rotators include a slip sheet in the manual about how to avoid this. It's a variation on the old Hy-Gain tightening sequence trick -- first tighten the mast clamps on the mast
I'm curious why nobody seems to be representing these well-reputed rotators in the United States. They have an export agency in Japan (Tokyo Meisan) and their rotators appear to be potentially compet
I may be living in a fool's paradise, but I figured that with 2 bolts per leg per joint, plus the zinc-on-zinc contact of the legs on top of one another, pressed together by the weight of the tower a
Yes, everyone please consider whether your response to a list posting should go to the list and not just to the sender. But please let's not make that the default -- I belong to only one list where i
This is frequently a function of mail server problems. Somebody fixes and reboots the mail server and, rather than maybe lose outgoing mail, decides to send everything on the last back-up tape again.
IF this were such a big problem (like 20 ohms in series with the feedpoint impedance), wouldn't the feedpoint impedance jump around crazily under keying, as the applied RF power burned through the co
Here's another data point. The 50 feet of Rohn 25 between my shunt feed ground and the tap on the tower, plus 50 feet of #14 copper, measured under 0.05 ohms on my DVM -- actual reading was 0.0. Whew
I carefully specified that the resistance was presumably less than .05 ohms, since my DVM read 0.0, rather than 0.1. 73, Pete N4ZR Sometimes a tower is just a tower
Let's face it, there are a lot of practices out there that probably have no actual merit, but are done anyhow. 73, Pete N4ZR Sometimes a tower is just a tower
Another alternative is a small mobile antenna. In the early 1970s I had a Hustler mobile whip bracketed to the metal balcony rail of a garden apartment, tilted out away from the building at roughly 4
Actually I asked about this not long ago. Here's what I was told. You'll notice that the television remote trucks have a rotating dish on the top of their pneumatic masts, and they coil the semi-rigi
It's also worth mentioning that the C-3 comes in a Dxpedition version with no tubing longer than 4 feet. The whole thing only weighs 32 lb assembled. I have VERY little upper body strength, and this
I want to be able to switch two feedlines to two radios in a foolproof fashion, such that I can instantly put my second radio on the first radio's antennas, or vice versa, and not risk feeding the ou
Thanks for all the many replies -- really too many to acknowledge all individually. Simplest solution suggested was DPDT switches or relays with the non-moving contacts cross-connected "X" fashion, s
All of these are variations on the fence post driver that is used hereabouts for driving T-posts for electric fences. The drivers are ~$20 at the local farm supply. They lack some of the bells and wh
You can rent hammer drills with the appropriate attachment that will do this job pretty well. But if your rock is hard, which I suspect, you may need something that comes on a flatbed trailer. 73, P
