My *first tower* (a 100 crank-up including the mast) is scheduled to arrive in mid-October. It will be located 150 from the base of my house. The problem is, *my shack is located on the second floor
I also have a 2nd floor station, I have no RF ground. W8JI has information in his site regarding second floor grounding http://www.w8ji.com/second_floor_grounding.htm John KK9A My *first tower* (a 10
Likewise here. 2nd floor shack without special grounding. Bob W3YY _______________________________________________ _______________________________________________ TowerTalk mailing list TowerTalk@con
It shouldn't matter where the line of demarcation is between open coax and the coax running through the conduit. Whether you run the conduit to the top of the tower and put your polyphasers at that p

I forgot to mention, I do not know of anyone running EMT to their tower, especially those of use with long runs. Surge protectors closer to the equipment would be more beneficial. I also have a 2nd f

The main reason to ground the coax at the top and bottom of the tower is so it doesn't arc to the tower. The tower being large will have a lower impedance to ground than that of the coax and will al
Sure there are better places to put the polyphasers. My own are located where the coax penetrates from outside to inside the building. The point was that they need to be put at the "boundary" between
You're confusing bonding of the coax shield to ground, which is important, with protection of the electronics, which is also important. Bonding should ideally be done where the coax enters the buildi
I've read several suggestions that the coax shield should be bounded at the top AND at the bottom of the tower. This makes sense to me for all towers except crank-up towers. I would think that for a
Yes it is a problem with crank up towers. But to not bond the coax at the top and bottom would make the problem worse yet. The coax is always going to share part of the current on a tower whether it
