Thread: Codan 9350 mounted on rear of DII - pics

If the upper section was below the top of the bonnet a lot of signal toward the rear would be blocked.

You will notice in the pics above showing the rear mounted Codan autotune that the upper section above the roof line. Also if you look at a most rear mounted Barret autotunes, only the whip is above the roof line.

yes that is where he wants to put ours on the defender...hmmm it may be a pain for the passenger though..


Mrs ho har

Hello, I have been doing a search trying to find where I can purchase the rear wheel carrier mount for the HF antenna. Would you be able to post where you bought it from and would you knonw if they fit a 1993 D1??

Thanks in advance, George.

Sorry everyone, I obviously missed this thread back in November.

Thanks Peter for enlightening us all.

Personally I don't like antenna tuning units on the bull-bar and that is why I posted the pics from Peter's setup. Yes Mrs Ho Har the antennae in your line of sight is a pain.

My GSM antenae is permanently on the passengers side of the bull-bar but as I'm usually not driving it's not a problem, however when I switch from the low gain UHF on the scuttle panel and fit the hi-gain on the bull-bar it is right in my line of sight. The consequence is, I want to cock my head to one side or other to look past the side of the stick. I'm tempted to weld another bracket in the middle of the bull-bar and move the Hi-gain but the bar is powder coated and so welding means a strip and re-power coat.

Left is a 9 foot 27MHz CB tuned by an SGC SG-237 auto-tuner mounted directly under the antenna. Used for HF. This is bent back and tucked under the roof rack when not needed.

Centre is a Comet SBB5 which is a dual band VHF/UHF.

Right is an RFI CD900 for UHF CB.

The bar is the "new" ARB one. I don't have any problem with the centre antenna. In fact my view is directly between the HF and VHF/UHF antennas. Forget they are there while driving.

Thanks Miky but I do notice that your whips are thin wire designs, you may have a different opinion of the obstruction if the antennae were more rigid fibreglass or even a multi-tap HF.

The wire whips have advantages when passing through the bush, however, as you would know, their nature of bending away from the prevaling wind (direction of travel) alters their fore and aft propagation, impacting communication on the move.

Yea. I take the view that most things in life are a compromise.
My last 4x4 (not a LR) I drilled holes in the roof within a week of getting it - new vehicle

As for moving whips as your driving... I am sure we could have many long and philosophical (and technical) discussions on that one
