I have a similar setup and you are dead-on. I have the rotor mounted at the joint between the top and next to top section. My top section is a flat top thrust bearing compatible section and so I have
I have the same rotor and observe a similar effect, though not as frequently. I put it down to the fact that this controller has no brake and a gust of wind works out the give and backlash of the rot
^^^^^ This (wear) is the key reason for pinning - IMHO. Any one who has had a knurled nut slip in a tool the first time and get stripped knows how much harder it is to get any purhcase on it the seco
Check out this month's CQ-VHF. It has a multipage article exactly on this topic and shows the procedure with multiple photographs. Rajiv, N2RD kind the before on -- FAQ on WWW: http://www.contesting.
I have had very bad luck with the big W2DU current balun. Three years ago I bought four of them for different wire antennas that I slung from trees. Two of them have already busted. 1. One had an int
quarter wave shorted stub to detune the guys. Imagine, if you will, a wire 1/4 wave long that is parallel to the guy wire that is open near the antenna but shorted to the guy at the far end. One cou
Commenting on Loos tension gauge: how to calculate the correct > value, it is another way to do it. The calculations would be harder as the guys are not horizontal. The the biggest issue is: How woul
How do the Yaesu thrust bearings (GS050 or GS065) compare with the Rohn TB3 for a 2" OD mast with a Rohn 25 flat top section? Regards, Rajiv, N2RD -- FAQ on WWW: http://www.contesting.com/towertalkfa
It behaves just like a vertical monopole with good low angle radiation. The actual low angle radiation depends on the ground quality. Regards, Raj, N2RD On Dec 13, 2004, at 1:05 PM, douglas.snowden@m
Ferrite 31 mix seems to be a good one for chokes. Raj -- Rajiv Dewan, N2RD n2rd@arrl.net FN13fc _______________________________________________ See: http://www.mscomputer.com for "Self Supporting Tow
Commenting on Tom's comment, the shift in frequency of x=0 point occurs because the characteristic impedance of the feedline does not match that of the antenna. If they did, the x=0 point, as measure
The stick at high noon is a very good method and a lot more useful than stars at night. You do not have to live exactly at the time zone meridian. You just have to find the sunrise and sunset for *yo
Just a few ways in which the Green Heron is superior, (working off of memory) - works with almost any rotor, including prop pitches, tic rings, tower turning systems, etc. - will work with AC or DC m
How about just a skirt, made of plastic of wood that goes around the tower and is tall enough to be above the snow line. Plastic sheet might just do the job. Raj, N2RD -- Rajiv Dewan, N2RD n2rd@arrl.
