Thanks guys, Just trying to stay sane, hi hi! Missed a 0 off though, 1kw would be 100mW at the other connections but truly I think it can be discounted as said. Don mentioned achieving 60dB, I'm not
Some interesting info here about how some of the commercial products are built. Pretty sure I must be doing something wrong here though. Okay this is just on the bench with a couple of pieces of coax
Thanks Jim, My original question, or one of them anyway, was do I need more isolation than a single relay will likely provide? From your answer I'd say the answer was no, not necessary. Now this is (
I've thought about this one before and came up with the idea of using worm drive hose clamps. Where you have a split in the end of the larger tube and then using a compression worm drive hose clamp s
* How about making the 'wings' bigger by bolting something to them? Martin, HS0ZED Standard nut drivers work just fine on those, but you need to remember to mark the elements in a manner so they do n
The Yaesu will do 450 degrees, the CDE only 360. Only you would know if that is significant. I currently use a Yaesu and it is useful to me, YMMV. If you plan on it needing service 10 years from now
Thanks for all the info on coating for my fibreglass spreaders. To summarise I think: 1. They are already "furry" so I think I can get straight to painting them. 2. Either FRP resin, epoxy based pain
Evolution of the Four-Element Double-Driven Antenna. CQ 1983 December. Wonder if anyone might have a, er, scan, perhaps, of this article. Thanks Martin, HS0ZED _______________________________________
Here's my 2 satang(Thai version of a cent though somewhat smaller) worth on the clamp connectors. I bought some at a local outlet here who offered both Taiwan made or Japan made. Being a ham (cheap)
Reminds me of the old joke: Microsoft and Apple like to think they introduced the world to point and click but I think Messrs Smith and Wesson might dispute that. Point and shoot? 73 Roger (K8RI) ___
I don't fully agree with the way it is shown on that picture. I would rather see the grounding wires taken straight down and the feeders swooped off to the side, observing minimum bend radius of cour
Heh heh! Yeah go right ahead and slide the conduit over the bunch of LDF. Will work just fine right up until the day comes that you really need to pull one out. Been there done that. Now it's 6" mini
return spring is broken and the tape is not moving. Most likely a big mess of it snaked up in the housing. Disconnecting the braid is just giving you some random length wire antenna better at pickin
Like I said, I have little specific knowledge here, specifically 5 SteppIR failures, 3 were drive shaft failures, 1 a corroded return spring and 1 a bad connector. But they are the only 5 SteppIR ant
Try this. Turn the rotor motor unit so that it is at the most ccw position (0 degrees). There should be a couple of index marks on the motor unit that almost line up when at that setting. Remove the
A tower trolley. I have a free standing 24m tower and am contemplating a trolley system to aid raising and lowering antennas and to remove most of the need for climbing. I'm aware of the Hazer system
Can anyone ID this rotor, well it says Telrex I know. Looking for info. http://tinyurl.com/78r5nk8 Thanks Martin, HS0ZED _______________________________________________ ______________________________
Thanks John, Will likely try to move tis one on in due course. It certainly does seem to be very heavy duty. The control box looks like an old hygain unit but need to check that out more. 73 Martin,
Just added another picturte of what we think is the control box that was used with this rotor. Same link http://tinyurl.com/78r5nk8 Martin, HS0ZED The original Telrex control box was about 12"x12"x4"
Thanks to all for the information about the Telrex rotor. If anyone has a scan of the catalog with it in or knows of an online version I'd like to see it, thanks. Regards Martin, HS0ZED _____________
