I can try to check tonight in the assembly manual. Maybe it has the spec.

There'll be a rocker switch on the dash for Antenna Up & Down, really hasn't got anything to do with the radio.

Also, there's a conduit that goes under the rear seat to protect the wiring. They're tough to find in good shape, but I've sent out a couple that I'd found in the wreckers.

I will take a picture of the antenna mounting on my 69 Parisienne tomorrow and post it here. 

lov it i want one to !

 

I'll take a measurement on my 69 2+2 which has a factory rear antenna and and my 69 American car with power antenna and post both tomorrow. A few thoughts though...

a power antenna wasn't offered on any 69 Canadian Pontiacs, only the chevy spec manual rear antenna option (offered repro, it was used on Camaro, chevelle and Impala series)

the power antenna switch mounted on the far left position on the dash (to the left of the power top switch). The system was manually controlled with no connection to the radio. it only went up or down when you operated the switch.

I wouldn't set up your antenna to work automatically with the radio, two issues: first there are no limit switches so the motor will keep going till you cut the power which will wreck the teeth on the motor in no time, second the mast is very long when fully extended, looks silly and gives bad reception for FM (FM likes about 30" of mast, too much you get echo and flutter)

a factory (US model) power antenna isn't located in the same place as Canadian rear antenna cars

the Bonneville and Catalina power antenna's are mounted the same distance from the front of the trunklid so the bonneville power antenna ends up being 6" further from the rear bumper say than on the Catalina because the Bonneville has a 6" longer rear deck

the factory power antenna mounting setup for US big cars won't work properly on a Canadian car because the inner wheelhouse where it bolts to is quite different in terms of shape and location

However you can easily fabricate a small lower bracket to anchor to the lip of the wheelhouse (Ames sells the GTO lower clamp in repro that probably would work better than the one you have)

Make sure you ground the body of the antenna to the car body just under the pinchweld for the trunk weatherstrip. A weak ground will really slow up the motor operation.

These pics are the factory install on my 69 Catalina ragtop, Bonneville is same setup.

Same switch arrangement in the wagon as the Catalina

 

 

Thank you John(North)

Awesome pics and information.

The 1969 2+2 East of Port Hope, Ontario, may be the one you spotted earlier this year.

It was for sale for only a short time.

350 but fully optioned car otherwise.

The current owner did not know a lot about the car.

I did not get pictures and the owner did not want his car on anywhere on the net.

Too late

It was posted on Canadian Poncho twice, could not find the first post from the estate sale but this one you can click on the photos in this post.

Note the dash, just power top.

If only I could go back in time and got a good look at that system he had.

Must have been aftermarket.

The thing on the right in the very first photo of the thread is the rear seat cable guard. It protects the coaxial and power cables under the rear seat cushion on the passenger side.

I measured the factory installed antennas on my cars, to hole center measured in inches in all cases:

Rear manual on my 2+2;
From forward edge of trunk lid back to antenna... 14.5
From sharp outer edge of quarter to antenna... 2

Rear power on my Catalina (same on my Bonneville)
From forward edge of trunk lid back to antenna... 11
From sharp outer edge of quarter to antenna... 1.5

The farther out to the right location on the Catalina is probably related to the mounting point on the inner wheelhouse to insure left to right verticality. The reasonFor the Catalina antenna being further forward is probably related to its greater angle, ensuring that someone walking around the car doesnt get an antenna tip in his face

The reason the 68 and older Canadian Pontiacs had a vertical power antenna rather than angled like the Catalina is because they were Chevrolet antennas.

Hey guys, I really appreciate all the help. Funny not one person posted saying "don't do that" If you go up to the top of the page and click the eBay link and search for these antennas you find the other 1969 has updated his price. He now wants $400 US Wow ! The is also a 63-64 Canadian one near Winnipeg.
