1. [TenTec] Antenna Splitter (score: 1)
Author: rohre@arlut.utexas.edu (Stuart Rohre)
Date: Wed Aug 6 14:53:45 2003
What you need is a switch, so that the impedance of each radio is not disturbed by the connection to the antenna and another radio. A splitter would decrease the signal level to each radio and cause

Even the Ten Tec device will attenuate signals 7 dB or over an S unit. Alternate switching will preserve the impedance character of each radio to antenna connection. -Stuart K5KVH

Very good specs on the splitters you mention. Of course, 20 dB is only a factor of 10 voltage, and would have to be factored into measurements. Where the dual hook up could fail is in monitoring the

Ideal grounding theory now advocates putting ring heavy conductor all around the house. Attach to this the power ground at meter, (in addition to its rod), telephone ground wire, and its rod; rig ent

Author: rohre@arlut.utexas.edu (Stuart Rohre)
Date: Tue Aug 12 14:25:46 2003
If all of the grounds are not bonded together, you can get very large voltage differences which are every bit as much a problem as the direct current strike of the bolt. It is fine to have a very goo

Jerry hit upon another major point. The grounding methodology cannot be separated from the quality or lack of quality of earth resistance in the local earth. What works on the Iowa plains will not wo

Author: rohre@arlut.utexas.edu (Stuart Rohre)
Date: Tue Aug 12 14:49:52 2003
The idea is any earth connection you have for lightning protection should have greater area than the conductor bonding any other grounds. The idea on tower grounds is to bond each leg to crowfoot gro

I question having a balun on a Windom. Since the true windom has unequal lengths of radiator either side of a feedpoint, it can never be balanced. The balun will be looking into an unbalanced load of

As several have pointed out, one has to evaluate the impedance of the bonding conductors and apply them only so far as you can still maintain a low voltage drop between the bonded points. Thus, it pr

A local friend ham got hit on a 2m antenna atop a one story house, and that was less than 38 feet. Certainly at 38 feet one should take precautions, such as static buildup dissipator atop the antenna

Eric has good points on a reasonable approach for the ham to protect his station investment. It is NOT Rocket Science, but applied Ohm's law just with larger currents, voltages, and lower resistances

With most of the ARRL Handbooks, you could design a simple filter for the output of a converted older radio to clean up your 60m signal, if needed. If you have a second receiver, you can use that as

Hi Bob, yes, a modern Windom (parallel line fed or coax with isolator) can work as an antenna, but it is never going to balance with unequal legs, so I suspect some minute RF at least leaks back onto

One thing we all forget after six years. Any antenna connection is going to weather and corrode so that we have some points of possible diode rectification to generate harmonics or intermod. Also, it

Check your power supply, and wiring to rig and connections like a burned fuse holder, corroded fuse, etc. You have more than a pot adjustment problem. It should do 100 watts output. 73, Stuart K5KVH

Well, for one thing about schematics for MFJ stuff. They do not put as high a markup on their gear as some manufacturers. It is possible they depend on the repair business from customers, or even cus
