Hello all, I had a close lightning strike that damaged some equipment, including my G-2800DXA rotor. It still works by using the left/right buttons, but the preset control doesn't work and neither do
I have never seen a service manual, but there should be a schematic in the back of the user manual. most likely its the box, but before you send it for repair disconnect the plug and test the motor p
To my knowledge, Yaesu does not repair the rotor or the control box. They will sell you the control box but its not cheap AT ALL! They will also sell the stand alone rotor without the control box. To
Regarding the issue of lightning damage to control boxes, I'm wondering if you guys are using surge protectors on your rotor lines or not? Polyphaser makes one and probably some others do as well. ht
Yes I use one, but built by Morgan Mfg., Model M-348, which I conveniently carry and it's a lot less expensive: http://www.kf7p.com/KF7P/MorganMfg..html Chris KF7P ___________________________________
I use Morgan M-348 units. The Wireman (thewireman.com) in SC (and probably others) sells them. 73, Larry W6NWS Regarding the issue of lightning damage to control boxes, I'm wondering if you guys are
They are still listed on Wireman as ICE units, model 348. ICE was changed to Morgan after the owner of ICE died a few years ago. They are listed at 64.40USD. 73, Larry W6NWS You sure about that Model
Ed: I'm using the Polyphasor models on the control line inside a steel box that also has my SPG plate outside the shack. In addition, I wound the control cable at the top of the tower, just before it
Plus the Green Heron uses transient-voltage-suppression (TVS) diodes which blow after an event (> 20V on two lines >80V on two lines). The diodes blow (self-destruct) so they are easy to identify and
I live in an area with high monsoon thunderstorm activity. I doubt that any of the protection devices would survive. I disconnect everything where it enters my radio shack. My r/v and deep water well

One thing to remember is that you need a rotor control line lightning protection box mounted to the tower "at the rotor", and also at the bottom of the tower. If you only put one at the bottom then t
Agree, disconnecting everything is the only reasonable means of protection. If your radio equipment is hooked to a power outlet and/or a computer, those connections will have to be disconnected also
Proper Grounding....???? Can we agree that a static crash/lightning/begins with a positive charge in Mother Earth, whether it be your Air Conditioner compressor/your vertical antenna/your tower/and o
Most lightning actually begins with a negative charge accumulation in the lower areas of a convective cloud. The negative charge in the cloud repels the electrons below it in the ground and man made
With the amount of metal a lot of guys have in the air (Bill, KC4PE has no small amount - I'm literally 10 miles up the road and have ogled his antenna farm several times. Hi, Bill!) and the number o

From my own viewpoint, I like the disconnect everything (if possible), but I'd add, I'd ground all disconnected leads. I say that, but very seldom disconnect anything unless I have plenty of warning.
THAT is one impressive and information filled manual. Gives me a lot to think about, particularly with regard to bonding the grounds at the AC entrance and the telephone entry box, both having separa
Well said David, Being in the cell phone construction and cell/broadcast tower industry for a couple of decades I find a lot of local hams asking me about grounds. How I get hit (as I have had) and t
