Car hatch mounts?

Post by Tim Tom »

Afternoon ladies and gentlemen.

Currently toying with the idea of putting a hatch mount on my car for antenna, I know that the best way to go most of the time is usually mag mount but thought might try something different.

Am I going to run into problems with swr with it? As fitted a custom made mount to a mates defender a few months back and had to run a completely separate earth strap as was poor.

Also what's basically everyone's opinion on them.

Cheers

Tim.

I've used magnetic mounts, gutter mounts and boot-lip mounts before now (as well as drilling a hole through the roof for a mount), but I've never fitted a hatch mount so can't say whether they're good or bad sorry.

Most people go for simplicity and removeability , so long as the aerial's swr is low and it's not all going to fall off the car.

I've just bought a bundle of CB stuff and there's a brand new "Antenna Specialist" hatch mount and cable that looks very well built but also looks quite complicated (good job it's new and comes with its instructions then).

If you've any warranty on the car then don't entertain drilling anything at all.

Cor that does look complicated. Nah no warranty, it's a old focus, probably about 15 years too late on warranty haha

Might just have to bite the bullet and see see what happens

Hole straight through the roof then. Job done ;)

Some mounts are adjustable so that the aerial can be made vertical, but also, some aerials have an adjustable joint on them, so if the mount can't be made to sit perfectly, this type of aerial will do the job instead.

Some people also just get some pliers on the whip itself and physically kink it so it's vertical.
Animals :crazy:

That's not a bad idea, I know theres a lad down my way who has his in his peugeot but for some daft reason, he's body mounted it at the front of the car on the roof near his windscreen, and then tilted it right back so that the top of the antenna is near enough in line with the rest of his car, if any of that makes sense... Looks a bit of a wally to me, but thats just me.

It's possibly been done to stop it whacking overhanging tree branches and multi-story car park roof beams, but he'll lose some of his signal as it makes it directional (it already is where it's been mounted too). As central as possible, or central but slightly to the rear is usually best.

In WW2, the Wiley Jeeps had 9ft whips on them for their radios, but they had to be tied back in an arc so they didn't collide with stuff. They could be undone to get the best range possible.

Nice video Tim. I tried doing a Youtube vid' myself a while back and it froze half-way through for some stupid reason.

If you do fit a spring under the aerial, you'll have to re-swr your aerial as the spring will be lengthening it! It might even mean you have to cut several inches off the whip, so see how you get on with it as it is first mate.

Yeah I thought that might be the case so for the minute I've left it as is, if i get bored and feel a bit wild I might buy one
