[OZAPRS] Need a hand - mobile antenna

Not when the antenna screws onto a shielded base such as mine’s SO239.

Does a spring base affect the length ?

Hi Folks,

One day I’ll actually get to ‘play radios’ again and be able to join you on air; but in the meantime have to console myself with reading the mail and storing up the good ideas; however in earlier times as Net control for the 14.116 Traveller’s Net, and even travelling o’seas (VK7 & ZL) I found the centre loaded Hustler system to work well on my 80 Series (bull bar) and borrowed/hire cars (tow bar). Simple, convenient, effective – and no I don’t own any shares.

Main components are HD spring loaded base, a common folding articulated ‘mast’ section  (1/4 wave on 6m) onto which fits coil loaded ‘resonator’ for whichever band – available for 80m – 10m including WARC.

My subjective observations were that it out performed the Codan 9350+ 1.8m SS whip on any given band.  


I presume they are still available – have not had to look as I have several sets including the suitcase-ready one. Just don’t try taking it onto a cruise liner or they will lock it in the hold!!! Rotten spoil sports!

The more I look at the vehicle, the more I read and the more I hear, the less I want to install something I'll hardly use!

I did consider a nudge bar but not at $800.

I'll build up a tilt-over mast for at home and populate it before I spend too much time on the X-Trail.

The main frame of the vehicle - subframe, floor pan, roof, firewalland door frames - seems to be a welded mass of metal to whichmudguards, bonnet, doors, etc are bolted, so any bolts attachingcomponents to the sub-frame could be a possibility. A "Z" bracketcoming out from under the bonnet could possibly utilise one of themudguard mounting bolts. A magbase on the edge of the bonnet could beearthed via a short lead to a mudguard mount or the bonnet hingemount. Most bonnets are not purposely earthed so heavy(ish) straps(RG213 braid, e.g.) around the hinges could be beneficial. A coupleof possibilities there, but this is just one specific vehicle. My days of crawling over and under vehicles to install radios ended a long time ago; these days I'm the wrong shape for crawling under, and multi-focal spectacles don't work well upside down under a dash. Ray vk2tv I've got a 32 series Xtrail.You forgot to mention the 8cm of insulating foam as well....My OM took out the passenger seat and got a base plate fitted to thebase of the seat, on which the radios sit, with one head on the dashand the other on a stalk attached to the passenger seat bolt.Antenna for 2m is in the middle of the roof and HF antenna on thebullbar. As indicated previously, motorising the antenna support costabout $45K.   -+-+-+-+-+-+-+-+-+-+-+LizVK2XSE_______________________________________________OZAPRS mailing listOZAPRS at aprs.net.auhttp://lists.aprs.net.au/mailman/listinfo/ozaprs
