Title: 1969 OEM AM antenna question.
Post by: 69Z28 on August 05, 2013, 09:07:22 PM
Hello everybody. I have a question or two, or three about the OEM factory AM antenna's for the 69 model year. Were the AM antenna's the same for A, B, and F models? If so was the tip plain or did they all have a groove middle way around it? Reason I'm asking is because I bought an AM mast for my 69 Impala that I'm going to assume is a correct oval type for at least the 69 Impala but not sure if it is correct only because I have never seen one for comparisons sake. This mast I bought has no groove around the tip. Is there something on antennas here on CRG? I didn't see anything unless I just haven't toughed on it yet. Just being curious. Was there a replacement that just had the plain tip?

The 69 Camaro AM antenna was also used on the 69 Corvair. The P&A 32 Accessories Manual shows the part number to be 986925. The full size cars used antenna P/N 993629. I can't help you on the full size antenna, but tips with and without the groove have been observed on the Camaro. HERE'S (http://www.camaros.net/forums/showthread.php?t=213829&highlight=antenna) some good info.

Thanks Ed. Looking at Fred's antenna in the link you provided looks like there are grooves in the mast as well but the tip doesn't look like it's grooved. The other pic has the grooved tip and it is shaped the same as mine with no groove. An AM mast, is a mast, is a mast, is a mast, correct no matter what model it was on. Would there be different ones for different models? I'm thinking there was one AM and one AM/FM mast for all models but thats just a guess on my part. There is an NOS mast on ebay right now.

Anybody else have OEM AM antenna pics to share?

I can't say if the masts themselves are the same. The part numbers I quoted above are for the antenna assemblies. Mast, base, cable, etc...

I've asked Warren to comment so stay tuned.

Thanks. Something I did notice looking for a mast, some screw in and some slide in the base.

The '69 Camaro AM antenna simply slid into the base, but it had two "teeth" on it that engaged similar "teeth" on the base so the antenna could be oriented with the chord of the "airfoil" shape fore-aft for minimum air resistance, and the stainless nut retained the antenna to the base.

3-'69 NOS AM masts, 1-'68 NOS AM mast for your perusal. The other NOS jacket, 370147, is the AM/FM solid mast. All of my NOS 68-9 masts have grooved tips, as does the original AM mast on my 01C X77 car. If you need any other detail pics let me know.

Steve

This auction is a '68 (and earlier) mast - bodies are completely different between '68's and '69's - mast cross section is the same, as is the length.

See the tag attached to the NOS mast in my pic #4 above - instructions on how to align the mast during installation; JohnZ always nails it.

And yes the masts themselves were the same between Camaro and fullsize

Thanks guys. Really good info. How's it going Warren? I didn't think there would be any differences really but just had to ask. I'm still curious about the tip though. Shaun from the SS427 website had one I bought that has no groove on the tip and was wondering why. Looks good overall and the tip looks the same as the ones posted but no groove. Just one of those curious observations I get. Should there be a groove or not? Probably need more info.

This website is great. I can't say enough about all the help you guys have given me in the past even for the common parts that fit other vehicles, this is the place to find stuff out. No messing around here, just straight to the point.

There was an earlier thread a couple of months ago pertaining to the antenna tip being grooved or not.   As I recall, some original cars had each.  My 09C original car has a non grooved tip.

This is what I got from Donny about the masts being the same:

""Yep. Flat with 1 groove on the top knob
AM that is. FM is a 30" spring steel whip."

One groove on the top knob? So the tip should have a groove then.

My Original 08C am antenna mast does not have a grove. Maybe it was a vendor change mid year?

Mine's original too (02D car) and doesn't have the tip groove.

Can we assume different vendors then? This would make identifying who manufactured it if there was an issue wouldn't it?

Because of your questions on the Camaro AM antennas, I pulled my parts out yesterday and took some photos:
antenna mast tip, antenna mast lower end with other parts,  mount and retainer from lower side with PNs, antenna connector showing 'chevy bowtie script'.  I could not find a PN on the mast itself, nor on the cable connector, but mine had an A-1 on the side opposite the bowtie emblem.  PN on the base (which fits against the fender) is:   3937665.   The pn on the lock wasn't entirely legible, but might have been 3943655.

and shown below is the assembled view.   The 'collapsed length' of my antenna is 18" from tip to the top of the retainer nut.

great pictures Gary. Very detailed. I wish I had your resizing skills

My original AM mast from my 04L Norwood built car has a groove in the top ferrule.

The mast I bought has the same plain tip as in Gary's first pic.

Hi Austin,  well.. it's not MY resizing skills, it's done by the Light Image Resizer software, recommended on this site by JohnZ many months ago, and which I tried and liked, and ultimately purchased.   It's quick and easy and does retain outstanding detail in very small file sizes.   After taking my higher resolution image, I first run it thru Paint to clip out the portion I want to post, then use the Light Image Resizer on the clipped portion.   You can repeat the process with lower detail until the file size fits the CRG requirement.   I think the images I posted this morning were 100kb or less each...   Try it.. you'll love it too! and we'll get to see more photos of your car too! :)  you can download and use it for free, but after several uses, it gets *slower* unless you purchase it.. :)    For $20-30 it's great.

And thanking JohnZ again for recommending it previously!  :)
