Amphenol, AMP, and RF Industries make good-quality crimp handles and
dies. The dies you need depend on the cable size as well as the
connector. Generally, 0.068, 0.100, and 0.128 dies cover most contact
pins, while 0.213 and 0.429 dies cover most ferrules. If you do a lot

Thanks for all the replies. One thing I hadn't considered was the audio delay
matching requirements. I was more interested in simulcast for frequency reuse
then using it for the same audio on multiple TX's. It looks like all you'll

Well, the specs for LMR400 (same frequency - same length) is 0.388 dB
and 9913 is .421 dB. RG-6 would be 0.932 dB.
So, if 0.34 is too much, the others you mentioned would be no solution.
