Using this calculator:
http://www.crompton.com/wa3dsp/hamradio/antcalc.html set for 42.5 Mhz yields approx. 66" length for the whip. I bought an ASP 96" whip and cut it down at the opposite end from the tip. If you use a hacksaw, be sure the blade is for stainless steel.

The ASP-121 whip is not threaded. It comes with and fits into an adapter (held by a set screw) which is threaded to fit into the top of the ASP-570 spring. It all works together with the ASP=3 ball mount and is what is correct for use on a CHP car.
 See the product tech sheets for all these parts here: http://public.fotki.com/Classicchp/s...ang_technical/

I realize that this is turning from a WTP thread into a technical post, but I'd like to ask for some clarification.
http://www.specialservicemustang.net/CHP2.htm The above link says that the whip was 96" in length, yet it was posted in this thread that the correct length was calcualted to be roughly 66". Which is it? I received an authentic CHP whip antenna that was roughly 66" in length (mailed to me from California with a shipping label folded around the shaft like a flag at half-mast). However, I really don't see how a 66" long antenna would reach the clip by the doorjam. Was the shorter antenna used without clipping it into the doorjam? Again, there seems to be conflicting infomation - just seeking wise counsel here boys!

Bill,
You are correct. It's a typo. The replacement whip is 96 inches in length, and has to be cut to fit. Mike C., If it's OK with you, when I fix the above in the Resto Doc, I'd like to post the brochure pic that you put into the thread.

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 - http://composite-laminates.com/canvas-C-CE-sheets.htm 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.
