Radio antenna

Hi Everyone,

 

I have a few questions about radio antenna's. Are all antenna's the same ? Is there any antenna better than another ? What radio antenna would you use ? I need to add an antenna to the truck. I heard that you could plug into the multiplexer, but I can not find one in the truck. My CB antenna goes right to the CB. The truck also has an after market radio. I am not into satellite radio. I would like to have a good antenna. I will add the antenna to the top of the mirror. What should I look at ?

 

Thanks for any help,

Al

Hi Al,

This info is not truck-specific, but generic:

 

For CB and ham radio the antenna is much more critical than for FM/AM reception, because you are transmitting as well as receiving. Hence the impedance match is important, and people talk about adjusting the SWR (standing wave ratio, a function of the impedance matching to the cable and the transmitter output circuit).

 

So to simply improve your FM reception (I assume you don't care as much about AM, as it seems to be dying out IMHO), you should be fine with any vehicle-style whip antenna that comes with an appropriate mounting base and cable. The only real challenges will be 1) routing the cable from the radio, out through the weatherstripping around the door, to the mirror bracket; and 2) finding a solid method to mount it to your mirror. Also standard car antennas work with the roof or fender metallic surface serving as a "ground plane" that allows the antenna to work as designed. Mounting on the top of the mirror, with no level metal panel below it, standard car antennas won't work as well. So if possible, find one designed to be mirror-mounted on a truck.

 

If your mirror is like mine, there is a threaded hole at the top, part of the internal aluminum casting that forms the structure of the mirror assembly. However a better option MIGHT be to find a mount that will clamp onto the round tubing. Google "trucker FM antenna". Here is an interesting discussion:

Here is one link I found that looks interesting:

http://www.truckers-store.com/store-products-amfm3-4ft-FireStik-AM-FM-Receive-Antenna-Black-Only_1097998895.html

but that Firestik antenna requires their Firestik mounting adapter, which I have been unable to find by itself online.

 

Finally here is a generic, inexpensive, mirror-appropriate antenna:

http://www.truckers-store.com/store-products-rp-557-RoadPro-28-AM-FM-Mirror-Mount-Stainless-Steel-Antenna-Kit-with-2-Shock-Spring_41223793.html

I suspect that would work as well as the original FM antenna.

 

Looks like a little project in your future! Good luck,

Pete

The 3/8-24 mounting they refer to is the standard threaded cb antenna mount, they just reference their mount as they want you to buy more of their "Firestik" branded stuff, any cb antenna mount will work.

Hi Pete,

 

Thanks for the info. Your last suggestion looks like a good option.

I like the idea of the spring.

 

I have a small side panel off the truck to access the antenna wire. I am also working on an idea to add turn signal lights under the mirrors. So far the brain is blank on ideas. I have seen turn signal lights on some of the long nose trucks. I am open for ideas there also.

 

Thanks for the help,

Al

i used some brake light strips on the outside edge of my mirrors on mine.(on the outside of the mirror running vertical) Bright as Hell (LED), wiring was easy.

Someone did a write up about turn signals recently (last year or 2). They used a mini van 3rd brake light that they mounted to the outside of the mirror housing. Wiring was run to the mid-cab turn signal light. I've thought about using some of those cheap LED strips from the auto section in Wally World that stick on. The red strips are bright and would get someone's attention.

 

As far as antenna's, in Amazon, do a search for Marine FM antenna's and boosters. There are some more options.

lou10,

 

Do you still have the pictures ? Can you post a picture ? That would be great if we could see a picture.
