The 3 dimensional effect has little to do whether you use a tube or solid state amp. It has more to do with how the speakers are placed in the room and the quality of them. A system that can maintain

Putting sealer between the connector and the block will increase the resistance and will not be as an effective ground for lightning. Even fractions of an ohm can have a large voltage drop in a light
You would not want to use aluminum strap in contact with copper. It will corrode away the aluminum in a short time. Burying copper wire for a ground is a good thing to do. However a very long run wil
Tom, Are you saying that it is not possible to decouple with a coaxial sleeve such as is commonly used on VHF or UHF collinear antennas ? It was used for many years quite successfully as a quarter wa

Hi Bill, Since we are on this ground radial kick, here is the best way. Run all the radials right up to the tower legs and attach them directly there. That will give you the lowest impedance ground s
Hi John, Don't know what the modeling programs say about it but I can tell you that although it may sound like an impressive ground it is not. It gets too long and the inductance gets too high to be
This thing is getting long and drifting off the subject of radials. Just a few notes on the other stuff: When I say don't pay too much attention to the NEC codes I am talking about what is and is not
Maybe I am missing something here? Why would anyone want to use a center connector on a dipole with a PL259 coax connector? Seems like you create a lot more problems keeping water out of the coax wit
You should put holes only in the bottom of the box for mounting. Then leave a vent hole in the bottom for drainage of any condensation. I have a couple of large electrical junction boxes with the lid
Bill, Go to the zoning board. They may be very happy to give you a variance if you want to put up a smaller tower. 73 Gary K4FMX Bill Powell wrote: I'm finally getting around to erecting a tower but
Frank Donovan wrote: The modern design practice is to bond all RF cables, rotator cables and control cables to a common grounding "window" at the entry point into the home. All other cables (AC power
To be completely properly done, the AC power should also come in through your bulkhead "ground window" with power line protectors at the ground window. It doesn't take much of an impedance difference
It doesn't matter if conductors are round or flat. It is the surface area that counts for low inductance. Of course a flat conductor will have less copper for a given amount of surface area compared
