How can you verify that your anntena is working correctly

[JohnOlanMills]

Humor me if this question is too obvious for some but I have a sneaking suspicion that my antenna is not working correctly.

It is on a tower clear of any obstacles, no obvious breaks in the line, it is about 30ft in the air so I can't just take it down so easy.

Can I check with a multimember the ohms or shorts, and if so what show they read.

Thanks Guys,

John

The Ohm value of coaxial cable e.g. 50 Ohm is the wave resistance or the characteristic impedance of the cable. This value can't be measured with a multimeter.

If the cable isn't faulty, you would measure a high mega ohm or giga ohm resistance between the core lead and the shield lead of the cable, regardless if the antenna is connected or not. If you measure some kilo Ohms or below it is possible, that the cable or one of the connectors is drowned and corroding has started.

More is as far as I know not possible with a DMM.

John,

I would contact either [email protected] or [email protected] and they might be able to help you out as well ?

Yesterday I took a multimeter to check my antenna cable and it shows a dead short, I could only test the end of the cable, I have the antenna on a tower with a tall pole, maybe 30', so I will have to take that one down and replace it.
