thats the good thing about the sf, most things i modify i just grab a spare for a few bucks when im at the wreckers.

I did exactly that, with some inner tube rubber cut to sit behind the bracket. You'll get better reception if it can't flap around as well.

A fair question, mate, and one that should be given considerable thought.

However, the space behind the dash fascia where the row of switch blanks are is completely empty. there must be about a cubic foot of free space, and it is open to the driver's foot well at the bottom. At a pinch, and only if it became a problem, I could puncture the D/S ventilation tube and force air over the heat sink ...

I also think that Oricom have designed the unit to operate properly at these sort of temperatures. At least, one would hope so!

Another solution is to extend the aluminium bracket I am making, attach it to the heat sink on the rear of the unit with copper bolts and washers, then attach a PC power supply heat sink to that. I have dozens of these lying around ...

I have just finished a very rough mock up of the bracket to attach using the P/S bonnet hinge bolts. Used an old bit of downpipe ...

I will upload some photos later.

It is basically a double "Z", and I will drill some small holes (3x 4 mm or so) into the vertical part of the hinge flange; tap a thread into them, and put reinforcing screws through the bracket into them. I have a blind tap for this size, and plenty of little bolts. Using a suitable thickness of alloy plate, plus having the bracket fixed to the bonnet hinge in two directions at right angles to each other should make it steady and strong.

I also intend to make up two right angle braces to strengthen and stabilise the antenna mounting platform. I will rivet these in place at front and rear. These should also protect the antenna cable.

Anyone doing this should be aware that you should not remove both the bonnet retaining bolts at the same time.
At all times, I had one bolt fully inserted, but just loose enough to manoeuvre the template into position when I loosened and removed the other bonnet hinge bolt.

The good news is that the aerial clears the passenger side door with both the stubby and the whip fitted.

The other good news is that the top of the stubby appears to be very slightly higher than the roof line, and the whip is considerably higher. Hard to tell in our driveway, as it has a fair slope on it.

I plan on having plastic side protectors everywhere the bonnet or guard might tend to rub ... You are only too right in saying that these things move around plenty, they can be subjected to fairly massive forces at times, as are all parts on a car.

Just heard that my trailer will be ready in around half an hour, so will toddle off and pick it up. Unfortunately, the OzTrail camper 6 tent I have ordered will probably not arrive in Mildura until Monday week. Ah well, I have plenty of jobs to fill in that time ... .

RB,
I have been studying your photos. Most helpful. I have prised out the two blank switches and will investigate cutting the bracket. that is the tricky bit !
Cheers

^ Thanks, HC. Glad that they were of some benefit.

Probably be a lot more so when I get time to write up the process, but it is fairly self-evident from the photos.

As I mentioned in this thread and to you personally, the switch frame becomes progressively more flexible and fragile as you remove more and more material. It pays to be careful at this stage!

I take it that the login process worked OK?
For obvious reasons, I cannot really test it from this end!

Login certainly worked ! Given how little the radio weighs I really don't know if it is necessary to brace it.

Hi RB,
I will send you a PM as I want to ring you to discuss the installation. A problem shared is a problem halved !

Thanks for that confirmation. Good to hear.

Mate, anything of this nature needs a lot more strength than one thinks to hold it securely!

I plan to brace this with a custom-made mount that not only attaches to the radio, but has 'wings' coming to the outside of what's left of the switch frame to both brace the switch frame, and better secure the radio.

Like the aerial mount I am making, I will take lots of photos, and will post precise measurements once done.

Hoping to commence the installation of my unit this weekend weather permitting. Unfortunately I have no undercover area

^ Good luck with that HC. Hope it goes well for you.

I have to start work on making the aerial mount; finish off the install of my unit; do the aerial and power wiring; find a spot to mount the handset.
