Hi guys need some advice, I am about to fit my CB and car stereo to a roof console and I intended fitting roof mounted antennaes for both .
Now I have heard that I dont need two antennaes I only need to fit the CB aerial and put a ''splitter'' in .I was told that the marine industry have been doing this for years is this true? If this is correct what happens to the stereo signal when you receive a broadcast. Help as I will be doing the fitout in the next few days :confused: :confused: oh and Merry Xmas to any tragics reading this today :p :p

Firstly the plural is "antennae" although "antennas" seems to be coming into use. :D

The stereo signal (By that I assume you mean the left and right channels) will not be affected by the use of a CB antenna and a splitter.

As to actual reception, I haven't tried it but I see no reason why it wouldn't work. I'm not sure how they stop the 5 watts of transmit power being whacked down the aerial lead into the car radio when you hit the button. I assume it has some sort of band-stop filter.

Goddammit Ron you got me all nervous now I can feel youre presence hovering over my key board. :p
I am going down to our local marine place today and will try and get some info
Will post up the results

We aim to please. :D

Let us know what they say. I've never investigated the splitters so would be interested.

I'm considering something similar but are you putting a uhf or a 27mhz in?

I have heard that uhf aerials are not as good as 27mhz for stereo rx? was from an unreliable source however.

I've never tried it with a UHF aerial, but have been using 27 meg whip antennae for normal car radio for years - fitted one up on my shed last week. I find that they generally give a better reception than most car radio aerials on the market.

Having said that - have never had both CB and car radio connected to the same aerial, so cannot answer the original question.

Neither are tuned anywhere near the FM broadcast band (or AM broadcast), but the increased length of the 27MHz versus the 400MHz antennae (Note use of correct first declension plural, Ron) means that the voltage output from the antenna will be higher for the 27MHz antenna, but both should give adequate performance except in fringe areas.

Went to Two different places and the message was loud and clear
It simply wont work on Uhf but is "ok" on 27Mhz and whatever the Marine frequency is.
I will be installing my rooftop antennae :p today if the weather holds out

Also noticed ( and I'm sure meets Ron's approval ) that you are using the correct abbreviation for "megahertz", which is MHz. A lot of people abbreviate it as "mhz" or "mHz", the latter would literally mean "millihertz" which would be a fraction of a cycle per second. ;):confused::D. Oh don't you love pedantry.

Well Ron do I get the nod of approval or not :p
