The forces on elevated guy points are MUCH different than straight in anchors. Not only aren't they pulling against the soil the way a normal anchor is but they have to deal with overturning and upli
If there is a variation of these now with only 4 wires they are probably sharing a ground between the motor and indicator. A new manual is what you need, all us that have the old g-xxxxs/sdx series u
If the balls rub against each other they can't roll so having the race too full could increase friction. Some bearings have nylon spacers to evenly distribute the balls around the race to avoid this.

The 'double extended zepp' would sound like a 'center fed zepp' which is as far as I am concerned a confusing term. I think they have picked up on the length of the wire used for a normal zepp and fi
Now that's a new one on me. Loops in the walls... well if they are all around the room and well bonded to the spg and at all the seams I wouldn't think they would cause any problems... of course they
I use those with the wires spaced about 1' apart, they are supported about every 75-100' on posts with spreaders. The ones I use have the reflection transformer at the far end and 2 transformers at t
You have a 40' tower and can get at least 22' from the base for your poles. Then you are going to have to dig a hole. Then you are also going to back guy the poles 3-4' from the tower from the tower
Now that's an idea... I wonder how much I could charge for a night for all this aluminum?? David Robbins K1TTT e-mail: mailto:k1ttt@arrl.net web: http://www.k1ttt.net AR-Cluster node: 145.69MHz or te
Yeah, but you also get the patent application, trade mark application, and 2 domain names! And of course 'Any knowledge' the inventor may be able to provide, apparently on any topic as it doesn't res
The local company should know the expected conditions and be able to add an appropriate additive if they think its needed. Covering and keeping it moist will help it cure, and curing gives off heat.
In my opinion rope guying is only for temporary use when putting up or taking down a tower or for no longer than field day lasts... and then for nothing higher than 40-50'. If you are putting up a pe
Now that my long summer vacation is over its time to wrap up what was probably the longest project of the summer. I have just put the final touches on a book I have been working on. It covers 21+ yea
Thanks to everyone who has bought my book, over 100 copies sold so far! And everyone says hams are cheap... of course I don't know yet how many of those are the expensive printed copy or the really c
I doubt if the copyright law says anything about who can or has to sell to who. It is mostly about who has the right to copy and distribute and for what purpose. You might however be able to plead a
Except for some very special designs all antennas are reciprocal... whatever effects how they transmit equally effects how they receive. So if more radials lowers the tx angle it also lowers the rx a
Doesn't look commercial to me... Slick maybe, but if its commercial he sure is advertising for a bunch of different companies, just looks like links to all the manufacturers of everything he has in h
Check out the msds at: http://rgmd.com/therm/msds.pdf looks like making electrical contacts could be tricky, seems corrosive to lots of metals, especially aluminum. Probably want to contain in tubing
