Hello need to know about earthing/grounding a venom 18ft antenna to my cobra 200 GTL DX rev 3.
As well as grounding the radio at lightning arrestor .Do I also ground the antanna?
Many thanks John
Hello John;
You can ground both the antenna mast and the antenna. your best bet is to place an 8ft grounding rod in the ground from radio shack or local two-way radio shop. Then connect the grounding rod to your mast. You can get a polyphaser from your local two-way radio shop this will connect between your antenna and the radio. it will also be grounded to the grounding rod. This should leave you in pretty good shape.

How do you have it installed? in a vehicle? or in a building. What power supply configuration are you using? Is it adequately earthed/grounded?
What type of antennas do you have?
waiting for your info :)
Hello John. A good earth ground for your antenna is more important than for the radio. Using the closest possible point to the antenna pole, preferably within a couple of feet, you need to ground the antenna pole to the earth. Go to a hardware store and buy a copper grounding rod which will be eight foot long and buy, as little as you can possibly get away with, some of 10 gauge wire and some kind of clamps that will attach the wire to the antenna pole and to the grounding rod. Google "antenna earth grounding" may help also.
Hello Jim. These radios do not work well with any power mic including the power echo mics because they have good modulation boards in them. But if you still want to try then check http://www.cbtricks.com/radios/cobra/200gtl_dx/index.htm
