So Motorola modified the Micor for the CHP
yet Antenna Specialist Co. made the Radio shop use an Adapter and hacksaw
for the Antenna.

I believe this is Mike C's pic -

In terms of the clip, I read that this is the correct stuff for the non-conductive material -

And according to mac88chp, the correct thickness is 3/8" (0.375"). So I could buy a 12"x12" sheet and cut several of these out on a bandsaw if somebody could provide me with the correct dimensions.

Fabricating the bracket from aluminum stock would be the next project.

Bill jr. is your low Antenna one piece or does it have an adapter set screw thing?

Thanks for the link Andy. The shorter 66" (estimated based upon standing next to it and judging from my height) has the same base as the ASP-121 shown in that link. The threaded, hex-sided base has three set screws that hold the antenna in place. The tip of the antenna appears snipped off and notched on two sides with a small steel ball with a hole through it that crimped to the antenna. Wish I could snap a picture, but the small detail would be lost with my cruddy camera.

Antenna length is determined by the frequency used to transmit. The CHP whip was used for their low-band communications which are in the 42 Mhz range (see calculator in my earlier post).

Bill - My 66" whip fits into the clip, which is installed in the original holes left on my car, like a glove. Note that the clip bracket on my car is not quite prototypical. The original has much sharper bends in it to fit the door channel profile.

Mike - yes, go ahead and use those data sheets on the site. Let me know if you can't download the original images and I'll email them to you. You can have anything else you find in that album for the site as well.

Michael, thanks for the confirmation that the 66" whip will fit into the clip. I'm still about 2 weeks away from getting my car out of the body shop, so I can't go out and test fit the whip at this point.

Would you be able to provide me (well, the whole forum!) the dimensions of the non-conductive clip? With that information I could make my own, and then fabricate a bracket to fit into the channel.

Bill,

If you are buying a sheet, and would be willing to copy one for others needing them, I'd be happy to send you my original. :)

I need the correct bracket as well.

Thanks Mike! I sent you my address via PM. I ordered a 12x12" sheet of the 3/8" material, and will cut them out once I have yours in-hand to take measurements from. I will fabricate the base as close as possible to what will cleanly fit the contours of the channel.

So that's one for me and one for you. I'm sure Andy will want one, as well as Rich (CHP8336). Not sure if Marcos needs one or not. I should be able to get that many cut out of a sheet, if not more, but I'll make as many as I can.

Good deal. :2thumbs: Thanks.

HOLY SMOKES!
 

I just rec'd confirmation that my order for the phenolic sheet has already shipped - WOW! That's fast. The price listed on their website is out of date. The 12x12" sheet ended up costing:

$43.50 material
$ 9.22 handling :No no:
$ 8.99 UPS shipping
-------
$61.71 TOTAL


Let's hope it doesn't bust apart once I start cutting and drilling! :eek:
