vhf/uhf 2m/70cm radio.

shot in the dark this post but hey here goes............................recently passed my foundation amateur radio licence (some in the know may have spotted my call sign to the left ) and i need to get a decent mobile antenna, so the question is what do you use? and where do you mount it and with what mount? needs to be able to withstand trees etc from laning. ive got a little cheap chinese antenna on the roof atm but its not brilliant so looking for advice on an upgrade.

im not a millionaire who can afford to spend £200 on a antenna so please bare that in mind lol.

THIS IS NOT A QUESTION REGARDING CB's SO PLEASE DO NOT ANSWER UNLESS YOU KNOW WHAT YOUR TALKING ABOUT.

Cheers for the response Martin, had a feeling you were a HAM enthusiast.

First callsign is a full licence........correct? Not sure on the others will consult my father (M0JSA).

Do you have a link to the diamond antenna?

I was worried the responce would be a front bumper mount as I have normal bumpers

Do you notice any drop in range from roof to bumper? Ive only got a little handheld pushing 5watts so any loss of range due to antenna positioning could be more of an issue..........like to listen to the local repeater (GB3P0) as it gets alot of use.

had mine stuck to the bonnet (it encorporates a mag mount) when I was last out laning as it lasted about 5meters into the first lane before it got took off the roof!!!

Hello, my callsign is lu2hc, and use VHF/UHF transceiver in my jimny

My old yaesu 5200 - vhf/uhf



ANTENNA: I’m suggest for uhf only good quality antenna (very high gain)

i´m install Diamond NR 790 vhf and UHF (4.5dB, y 7.2dB)





And coaxial cable (low loss (or low attenuation) in uhf).



In Uhf frequencies is necessary very good quality products, to achieve reasonable communication. (you can not save money)

Coax connectors must be low loss (eg amphenol)

little update:

went to "Waters & Stanton" on saturday with my Dad to look at suitable aerials that can deal with overhanging branches etc while laning!!anyway he conveniently (for me anyway) brought himself a new Yaesu 2m radio to go in his Defender so lucky me gets his old Kenwood km-v7 meaning i can stop using my Baofeng uv-b5 handheld also meaning i can now use 10w

so after dinner saturday evening (while the misses was at work) i set to work deciding where to mount my new Kenwood, after much deliberating i decided under the ashtray was the most suitable place as i need to be able to see it (unlike my Cb which is stashed under the glove box).......... the mount supplied was not suitable for the task so i set about fabricating my own mounting bracket. some time went past as i worked on a design and sourced some suitable metal, screws etc from my old mans work shop and construction commenced.

heres 2 pics of the end result:





so saturday night resulted in me mounting the radio and running the coax to the roof via the fm aerial mount on the roof.didnt finish till late saturday night.
sunday morning i ran the power for the radio direct to the battery going through where the clutch cable goes and picked up some longer bolts for the antenna mount to clamp it round my roof rack.

the first picture shows the antenna ill use for daily driving as i dont need to worry about length:



this second pic is of a cheap Watson MR700 with a 3/8 to pl239 adapter on a soft spring for laning (hopefully this will handle the trees and if not it was only £14):



monday i fitted 2 speakers for the radio one for each band, had to extend the wires and strip the drivers side interior out to run the wires but im happy with the result:



all in all worked out well and the little aerials work surprisingly well and provide a decent range......time will tell if they survive a days laning

Thanks for reading

Hi all,

Just spotted the section ... any suggestion for best place to fit and VHF/UHF antenna on the Jimny?

With magnetic is quite straight forward, but I'm looking for a mechanical/screw fit of the antenna.

Thanks,

I use this on the back door. Works great with a 1mtr whip aerial on it (but does clang on the back door when on scratchy lanes a bit)

Thanks - I'll have a look.

On the other hand, mounting it on the roof rack should be a good idea, but I don't have a clue if it will affect (negative) the SWR.

Till now, the best place to fit a magnetic base antenna is the center of the roof - due to obvious reasons, I can't do tests with antenna that requires drilling and "hardware" mounting.
