Hi all, Well, last weekend we got the tower up and I spent most of Saturday afternoon tensioning the guys and making sure the tower was plum. Tonight I climbed it again to do some more antenna/cable
Your response is typical of most I've received. I understand what you say. In fact, there's a little bulge on one side of each piece of the bracket. That, I figured out is so that it sits on the Z-br
This whole thing seems to be a bit of debate between people. To connect the tower to the house ground or not to. Most people I have talked to do not connect the tower ground to house ground. The simp
I just went and took a quick look at the tower. The assembly is not resting on a horizontal step of the Z-truss. I don't know how we missed that. It sure makes sense. So....does it need to be fixed?
Well, it looks like the consensus among everyone is to redo the brackets. So that's what I'll have to do. Just more work to do up top on the tower! :-) Right now, they are definitely not sitting on t
Me again! Another question (have lots with the tower just gone up!): I have a pair of PAR OA-50 Omni Angles that I have been using on 6 meters for the last 4 years or so. I had them mounted previousl

25G Torque Arm Stabilizer. Tessco Price: $148.80 Yes, they are still made. I believe the design is somewhat different now. But Tessco still sells the GA25GD guy bracket that uses the torque bars. So
OK, I am willing to be educated here on this whole issue. And as I new tower owner, I guess I should be. Here is how I have seen things: 1.) Ground tower to ground via network of ground rods. 2.) Use
Hi all, I've got a couple more grounding questions. I downloaded and printed out PolyPhaser's app notes on lightning protection. I've done a very brief amount of reading and it's raised a couple more

But if the lightning protectors are all tied into the same ground rod, isn't that the same as the SPG? Yes, but the box only shields the stuff inside the box. What about all of the coax that is run i
OK, so how does one ground the phone lines and Cat 5 cables? Do you need to run them into special surge protection devices or are there grounding blocks available for these? 73, Jon NA9D -- Jon Ogden
Phyllistran runs around 45 cents a foot if I remember correctly. EHS can be had for around 11 to 13 cents a foot. Jerry's right about some of the extra costs, but consider that you will need grips fo
Tessco sells EHS by the foot. Length of time does make a difference. Let's say I plan on putting up a 50 foot tower at my QTH. Now let's say that I think that in 5 years, I plan on moving and putting
Jeff, A free tower is certainly better than buying a new one outright, but it ends up being far from "free." I just put up 50 feet of Rohn 25 plus a 3 foot top section. The total cost for all that wa
Oh gosh, it goes back a bit to wave theory, but there's a couple of different "velocities" when speaking about interfering waveforms. The "group velocity" CAN indeed be faster than the speed of light
Thank you for the correction! You are right. Been a long time since I studied EM wave theory! That was a good refresher course! 73, Jon NA9D -- Jon Ogden NA9D (ex: KE9NA) Life Member: ARRL, NRA Membe

You may wish to try another option of N-connector type as well. Cable Experts sells a two piece N connector that is really nice. Works up to about 2 GHz, so it's not as good as a standard type N. The
