I want to get an external magnetic base antenna to increase distance. What do I need to buy and how do I adjust the radio for the antenna? Or do I need to adjust anything?

Swlovett,

The best out of the package antenna for a magnetic I have experienced has been the Wilson "Lil Wil". As long as the instructions are read and followed correctly and adjusted with a good working SWR meter you should not have any problems. Make sure the ground is good on the base, and adjust the lowest SWR on channel 20. Then check the other channels 1 and 40 to make sure the SWR reading is even. If you cannot get a good reading anywhere, check the ground and readjust the base. Should you continue to have a high reading you may have to trim the length of the antenna according to instructions included with the Wilson Antenna. Your radio should not need any adjustment and is factory preset and tuned. This is instructions for the "Little Wil", however, you may choose some of the more broadbanded antennas that are longer and easier to tune, although more pricey.

Receives very well- other radios can barely hear me-I have a short mag base antenna


The rule is the taller the antenna the better the reception and power output. Of course it is not always convenient to mount a 102" whip.
  • 4 watts into a 102-inch whip antenna, it is the same output as if you put 11 watts into a 3-foot whip.
  • 4 watts into a 102-inch whip antenna,, it is the same as if you put 14 watts into a 28-inch antenna.
  • 4 watts into a 102-inch whip antenna, it is the same as if you put 54 watts into a 7.5-inch antenna.

You did not mention the signal on their meter and how close they are. This may be a modulation issue. Wattage increases can go unnoticed volume wise but small modulation increase can make dramatic changes in volume to the receiving radio. Check that your dynamike or mike gain control is turned up clockwies increases it. The radio itself may need the modulation increased internally. If you have a powermike with adjustments on back it may be way to low. Hope this was of some help

Looking for a 21" antenna for a Motorola SP10


There are custom made antennas for portables. But the better solution is by eradiostore, use a mag mount.1) custom portable antenna, expensive.2) Motorola adaptor to BNC to longer antenna (portable, car type or base station).
3) NO power increase, not only are those frequencies designed for low power the board inside the radio cannot handle the heat and is not changeable or adjustable.

How far can I get this thing to reach,and how ?


With a good antenna, and the antenna tuned for best SWR, about 8 miles from mobile to mobile, and about 12 miles from mobile to base radio.

You can modify the radio and turn up the power, it will get you more range, and make the radio sound louder, but you will still be limited, because radio is line of sight. Hills and structures block RF signals. you go down a hill, you will loose distance.

With a cobra 29 that has been tuned up sitting on a hill about 1400 feet above sea level, I was able to talk to some one on a base radio about 50 miles away with out my amp on. I also have a very very good antenna. not something you normally see either.

With a clear on blocked line from antenna to antenna, you can talk really far on a stock radio. There is a saying for CB antenna's. "Height is might."

There are a lot of things that effect the distance a CB can reach.

If there is Skip active, you can possibly talk thousands of miles with a stock radio. Skip is when the ionosphere becomes charged by solar energy form a solar flair and causes the radio waves to bounce off them, making it seem like you have a straight line of sight to places that would normally be blocked by the natural curvature of the earth.

Then there are Linear amplifiers. They increase the power of the signal of the radio. They will increase the output range, but then you may be talking to people that don't have an amp, and that you will not be able to hear them because they do not have enough power to reach you.

So, get a really good antenna. Make sure it is tuned for the lowest possible SWR. Refer to the manual that came with your radio on how to find out your SWR, and how to lower it. There will also be instructions on how to tune the antenna that came with the antenna. Then bring the radio to a CB shop or a CB tech and have them tune it up. It will cost about $30.

With my radio barefoot, and can normally talk around 30 miles or more without worrying about hills and obstructions. (Barefoot means, without the amp on)

Dose it work good like i live in a prtty good nabor hood dose it get good distance will it conect withe other bigger cb radios


Typically, this type of handheld has a useful range of approximately 1-2 miles. This distance will be increased with other radios being mobiles and base stations. Distances of 5 miles is possible if the other person has a good base station antenna. I would not expect much from the stock rubber ducky antenna.

I just purchased two radios. How far will they transmit and receive with good clarity in the city? I need to transmit and receive from about six to eight miles away clearly. Thanks.


bobengelman,

Typically and unmodified handheld CB will have a decent talk distance of 1-2 miles with both being a handheld. Further distances can be had if one of the radios was a mobile or base station with distances of more than five miles with weak signals. In some cases the antenna can be changed to a better longer antenna. Extention type antennas typically transmit about a mile per watt. Conditions such as terrain will have an impact on signal specifically mountains or buildings. Better results may also be had by purchasing a mobile magnet mount with a PL-259 to BNC to fit the radio. A magnet mount placed on a air conditioning unit or large cookiesheet as high as possible will make decent gains for distance if the radios are intended to be stationary.

What digital antenna does it need to recieve stations. there is no coax connector on the tv


You will need to get an HDTV converter box. You can purchase these at various location (Radio Shack, Best Buy, Wal-mart). As for the antenna, your selection should be based on the radial distance between your house and the TV station towers (line of sight distance from you to the tower). Antennas will have mileage information on the packaging for reference. Select an antenna which will meet your needs. There are a few good sites which offer web application to calculate your needs. Check out antennaweb.org if you like. Hope this helps.

On my 77-099 Cb MIDLAND Radio I wonder can i use a antanna that is used for vehicle can be made for a home base radio place.I BOUGHT A MIDLAND CB RADIO AND MADE IN TO A HOME BASE RADIO THAT IS MADE FOR...


Generally this is not a good idea. The antennas that are designed for use with a car, use the body of the car as a ground plane. If you try to use this in a house (or even outside the house), it's not going to work.

Your only chance at even getting such a setup to work would be to attach the antenna to a LARGE flat piece of metal, approximately the size of a car, which is then grounded with a long metal rod into the earth.

I'd really suggest looking into buying a proper home CB antenna, which would then need to be mounted somehow to the roof of the house (or as high up as possible.) If this is not a feasible option, you should do a Google search for "CB Dipole Antenna", and get instructions on how to build and tune your own antenna. Dipoles are not overly difficult to construct, and perform quite well.
