Well I am about to make the plunge and drill a roof hole in my vehicle. Has anyone drilled a roof hole for a nmo mount in a 2000 GMC Jimmy without any complications?

I haven't, but W3LK has. If you look back a little right here on this forum, you'll get his input.

Fred:

Pop the dome light - you should have a clear access to the roof.

I just did 2 NMO mounts on my Suburban.

Placing the holes above the dome lights is absolutely correct.

Nice composter in the background too. They really work well.

James:

Just another thought on your installation ... you want to keep the cross bars of the luggage rack a foot or so away from the base coils on both antennas, if at all possible. They can have a detuning effect on the antennas.

I found out the hard way. Smiley

Do NOT use a drill mounted hole saw. Instead use a "Chassis Punch" which will produce a very clean cut through the roof. For most NMO mounts a 3/4 inch chassis punch does the job.

hi,

if the punch is too expensive for the budget,
the antenex hole saw 3/4" is nice.
replacement cutter is available when needed.

I realize this thread is fairly old, but I'll ask here anyway since I have a similar vehicle.

I have a 2000 Chevy Blazer and would like an NMO on the roof.  If I go above the dome light, the roof is ridged there and the antenna would have to be off-center, which I don't care for.  The non-ridged area ahead of the roof rack has a moon roof.  It looks like there is about a 6" area directly behind the moon roof where I could mount install an NMO mount, but I'm worried that the coax would get caught in the roof when it slides back into the roof.

Anyone ever dealt with this before?

Thanks
