Hi!!!
I own a Uniden 120XLT radio scanner.I was thinking to buy an external Antenna for it so that I can improve its reception.Can anyone suggest me a good form of antenna which is compatible with this model.Also please do tell me where its available in London and an approximate cost for a good antenna.

How much improvement in reception can I expect if I introduce an extenal antenna on to the set.Please do give as much information as possible.Thanx a lot for the help Smile

Hi Santosh,
I know I am not that young anymore, but please refrain from calling me Sir...
(though it was appreciated).

108-137MHz is the VHF airband.

Connecting an external antenna to your scanner can be anything from a small to a huge improvement, it mainly depends on how high and unobstructed your external antenna will be.
To make a comparison, imagine that your antenna are your eyes and that you are hoping to see as much light sources as far away as possible.

If you can find a junk external FM (radio) antenna somewhere, you got what you are looking for.
If not, an old Band I TV antenna would be fine as well.
If you find one or the other, remove any "parasitic" elements it could have on its "boom" (the spine of the skeleton), and keep only the one where the antenna cable connects to. (keep the boom and the bracket)
Mount your antenna vertically (the element to which the cable connects has to be in the vertical plane), bring down your cable and mount a BNC male connector at the end. (if unsure how to do, ask a ham operator or anyone with minimum knowledge)

If you prefer the "off the shelf" solution, look for a simple "quarter wave" antenna (it should be about 60cm / 2ft high)

Try the WBA-20 Airband Base Vertical from Waters and Stanton which is a frame page from their Main Site, or a Super discone from Moonraker UK which is what I have got.

You'll probably also need a connector from the antenna to coax and then from the coax to your reciever.

I've got mine mounted on a pole on a gable end, and can now clearly hear EGBB although I'm 25 - 30 miles away, as well as taffic over the Channel.

Santosh,
I see that you study mechanical engineering.
You should have it very easy to make your own antenna (for a cost of close to 0), want to give it a try ?

Thanx very much for the information.I will definetly try making one or introducing an TV antenna.I hope it will improve the performance.If that dosent work much better may be will choose the second option to buy one from the store as told by Timjohns.
