This will apply to all vehicles, not just Omegas

Easiest place to drill holes is on the roof above either the front or rear courtesy lights, making sure that the bolts and cables from the aerial do not protrude too far into the cabin to affect putting the light back afterwards - this will prevent from having to remove the roof lining.

Wing mounted aerials are generally avoided if at all possible, as can be a little directional in their performance, but OK as a last resort and certainly better than any form of glass mounted or internal aerial.

General rule of thumb, keep the aerial, upright and towards the centre of any large metal panels, and before somebody says that internal ones are ok remember that a TV aerial inside the loft will seldom work, yet put outside of the same house in the same location will give a much stronger reception - same is true in cars.

Oi! Loft aerials work fine  >:(....

...as long as they are about 5 times bigger ;D :y


Not sure the analagy is that good tbh, as loft aerials have advantage of static and unaffected by weathering and pigeons.  But your point is valid :)

I have a loft mounted TV antenna. Thought "that'll have to go" when we moved in, but it's actually superb. Then again, we're 600 feet above sea level and in line of sight of Rowridge transmitter. ;D

In a car, you're always going to find challenging reception somewhere so, if radio is important, and if you're going to the trouble of installing DAB it presumably is, get the best you can.

Groan . . .   :P

There`s always one (or two !!)  ::)  :P  :-*

 ;D
Joking aside, I'm in what used to be called a fringe area in the analogue days.  I have a largish (about 1.5m, with the X type beams on it) aerial in loft and get good analogue and digital signal with it.

As per most modern estates, TV aerials (and satelite dishes) are prohibited, not that anyone takes any notice of that for satelites.  Can't see a single tv aerial round here though...

Joking aside also, I wish that I could have put an aerial in my loft - we had a similar X pattern 1.9m Ultra High gain aerial bolted to the side of the house, as we are near the sea and the wrong side of the cliffs to be able to see any transmiters at all - problem was that every time the seagulls reach breeding time (I think its fortnightly - or at least appears that way) they would roger each other senseless whilst perched on my aerial and bend the bracket - we ended up going over to cable in the end as I was fed up going up the ladder each time to fix it  ;D

PMSL.


Mrs TheBoy's dad lives about 3 miles from main Oxford transmitter - big powerful bugger that one is...  ...can't get a signal due to living halfway up the wrong side of Shotover - I bloody great hill just South of Oxford, and has to point towards Newbury, some 25 miles away.

A mate of mine lived about a mile away from the Hannington transmitter. Moved into the house, installed TV and it worked OK but his Mrs. was complaining that the video didn't work. Eventually he looked into this, and found that the antenna connector of the TV hadn't been connected to anything, video included, yet his TV signal was fine.  ;D

Unusual that as TV transmitters often have a shadow of upto a mile around the base where reception relies on reflected signals....
