Hello forumites. Some time ago I had a new antenna installed on the gutter above the passenger door on my Hiace bus. All was good for about 8 months and then the metal bracket that was attached to the gutter snapped in half. No good anymore. So next time I was in the city I took it back to the place, told them what had happened and was pretty much told " hard luck". The bus doesn't have a bull bar and the only other option would be to drill a hole in the roof to install another antenna which I don't really want to do. Is it possible to buy a magnetic antenna for a UHF? Or have one made do you think? Thanks and cheers Toni

I have a magnetic base for mine, sits on top of my ute cabin roof. Works good, but the antenna lead is fed into the cabin through the small quarter window on the drivers side. You should be able to buy the base separate, the antenna just screws onto it. Can't remember where I bought mine, that was 25 yrs ago. Cheers.

G'day Kilcowera Station.

You can buy a magnetic base and fit a screw on UHF antenna no problems. You will need to run the coax from the base into your vehicle, which I presume you do know.
No sure where you would buy one but where you bought the gutter mount may be a start.

Cheers
David

GME do a magnetic

Mag mount

Might do the trick.
It has a thinner cable so you can maybe tape it in the door surrounding in to the cab

Depending what type of mirrors you have you can buy mirror brackets.

Yes you can purchase them GME part number AB406 and then fit a suitable antenna.

However long term use of a magnetic base have an effect on paint work and possibly metal sub surface. Plus it also attracts iron oxides which will also rub on paintwork.

I'm not a great fan of GME products period, the antennas are built light on and often have a sine wave effect when traversing on rough roads - I broke one steel wound spring steel unit inside 1 1/2 days, and think the fibreglass replacement I sourced had a hairline fracture within 1 week.

Probably a better idea to think out side the square fit up a minesite bar with the hi mount brake indicators etc -wire them up so they work, and use this as a antenna mount instead.

No drilling of holes and antenna is usually very short as well.

Company i used to work for did many hiace people movers (tall roof 6 foot plus stand upright in it) like this for BHP and FMG and worked well.

For antennas we only used RFI which is trade only but any radio comms outlet should be able to supply a suitable antenna for mounting this method.

We used CD51-68-73 for the UHF this has been superseded but is still available without coax cable for "field repairs" on site CD51-68-70 field tune-able ideally with SWR meter but can be cut using a cutting chart.

This antenna is a ground independent so designed with a load coil and can be mounted on less than optimal locations ie bull bar mirror mount brackets etc.

Prestige Communications in Perth offer "prestigious service", fast despatch & good pricing too.

Haven't checked their site for a while, but am sure they would offer a magnetic mount. In regards to fixing it on the roof, a small patch of thin plastic between the body & mount will stop any problems mentioned earlier.

Thanks for all your replies. Dean K3 how about you come and fix it up for us? What you say sounds good, but a bit beyond my limited electronic knowledge! but you have all given me some options to consider. The gutter mount that we had was not spring loaded and it just cracked. Will get onto it when next in Toowoomba. Or buy something online. Any more good suggestions as to where to buy would be appreciated. I don't care how the aerial is mounted as long as it works! Toni

I would if I was your side of paddock, tad far from Wait Awhile.

Really need to source from a dedicated radio communications supplier not a 4wd supply shop. Choices can be limited at times in some towns !

Think somebody-else has you covered as it is, however way I see it is if its been broken once is it worth going down same track. Better off thinking outside the square at times.

I see there are 2 magnetic ones the AE4020 and the AE4026 on that GME website. Would one be better? More powerful? Or just more expensive?

Hi Toni, If you can wait until I come out, I will bring you a GME gutter mount that I have left over from a previous life when vehicles still had gutters, is very strong and I'm sure it won't break. Cheers Ian

Buy this Toni

https://www.ebay.com.au/itm/ANTENNA-LEAD-MAGNETIC-BASE-ASSEMBLY-UNIVERSAL-UHF-CB-BAND-RADIO-UNIDEN-4784/401098051971?epid=1264033717&hash=item5d634e9183:g:IW4AAOSweM1aE9Nx

Its very small, less visible, and its cable is less than half thickness of others so it can go under door rubbers easily.
