I will ask a rookie question here, all this makes me wonder what would happen to antennas like the macov5/8 or the i10k which are built with radials in mind if you isolated them from the pole. Do they figure the support and feed line in their designs?

I may never get a chance to find out, we have had a few vehicle break downs this month which has really put a strain on the budget:redface: I would have the 465 looked at, I have a PC-122 in the wife's car. I have had it for years and it still impresses me, I have talked around 30 miles with it...

If you could do that you would be set for life :thumbup1:

I stumbled across a thread that mentioned the Alinco dx 70th. This is not a radio or even a brand that I have herd of before. Was looking for opinions on it.

Mine was doing something similar to this until I had it aligned, I think mine was because someone unlocked the clarifier and never aligned it afterwards.

I have a 979 in my pickup, it is a decent radio. The recieve is not as quiet as the cobra 25 I had in there before. I also get a little engine noise feed back from the external speaker, I think it may be coming from the talkback. It gets good audio reports, but it's off frequency some on...

You guys have a much deeper understanding of theory than I will probably ever have. I find this all very interesting though. I'm sorry if I derailed it some. Back to topic! :-)

I'm planning on getting mine from DTB radio, have heard a lot of good things about them.

I was saying that the antenna needs a groundplane to work properly, the metal under the antenna in the roof or the trunk lid is what creates the groundplane. Having a ground strap to some metal "next" to the antenna like the car on a hitch mount or mirror mount on a truck is not the same. An...

I have always been told that in a mobile antenna installation the metal under the antenna matters more than the metal next to it

I would think a Texas star dx250 would fit the bill nicely.

In my opinion there are better options, I bet a good magnet mount on the center of the roof will work as good as a 8' whip on a hitch mount. But if you need to cover multiple frequency bands it may be a different story

Which brings up the million dollar question, how far above earth does a vertical antenna have to be to be efficient? I would assume a monopole antenna should be higher than a groundplane. I know I have always been told at least 1/2 wavelength and that a full wavelength is better. Of course this...

Wouldn't this basically be a "trucker" style antenna then? Like the Wilson 2000/5000?

That's funny, I had it flip flopped in my head.... Even after reading all this:blush: I think I have it now. As for bonding, I did it in my F250 Powerstroke and it made a world of difference as far as engine noise, I'm not sure about transmit but it had to have helped there also.

That's interesting, I did not know they purposely isolated the guy wires. I agree that it is good to have the antenna balanced, but what about when the coax shield or vehicle body becomes the other half? This situation is not a resonant length... Is it perfect? No but it does work fairly well...

I am a bit of a late comer, and my technical knowledge is limited, and I know that this is a discussion about the terms used. But it made me think about a picture I saw in an article I read about the WLW station. I have to wonder if the "Guy wires" that kept the tower erect didn't create an...

I actually have around 30' #6 THHN copper laying in the barn left over from when I did electrical work that I plan on using.

Thanks, I was looking at the VR 9000 also for that reason. But she likes the modern styling, and I was looking for a little more punch to talk across town over the hash, and for some fun on DX

I actually have an ar-144 too:thumbup1: but like I said I would like the ability to freeband, and I would like an all in one unit for the simplicity of it.
