" ... oddly enough, Amazon has lots of coax crimpers ... "
Amazon.com: coax crimpers
Back in Dec, 2011, I purchased:
Coax Compression Connector Crimp Tool for RG58 RG59 RG6 F type Compression Connectors - Crimpers - Amazon.com
and
http://www.amazon.com/gp/product/B000JNNWQ2/ref=oh_aui_search_detailpage?ie=UTF8&psc=1
and
http://www.amazon.com/gp/product/B001EKCGT8/ref=oh_aui_detailpage_o02_s00?ie=UTF8&psc=1
along with several multi-packs of various connector tips/ends(?), and a hundred feet each of a few of different "breeds" of coax cable.
I had never crimped a connector before in my life and it turned out that I was not very good at it. Nearly all of my crimping activity was related to the antenna feeds for several scanners. The above equipment was not the fault, it was my mental and physical incompetence with the category (electronics).
But (not luckily), I had an ace-in-the-hole. An ace that I saw coming when I knew the EXTREME Option for the HP-1 Scanner was becoming available. I foresaw before actually acquiring the EXTREME Option , that the "Analyzer Functions" could possibly determine antenna quality. As it turned out, the "Analyzer Functions" could better be described as determining the "overall" quality of the signal at it's entry into the scanner, the antenna only being one factor.
Bad crimps, along with differences in antenna, cables, connectors, multicast "sites", etc., were determined in short order by the "Analyzer Functions". I won't go into the complex details now, as I did that at considerable length back in 2012. My reports were not favorably received here in the RR Forums (except by a very small group), and these poor receptions caused me to take a 18 month hiatus from even signing on to the RR Site.
Anyway, I fully support online purchasing (99% of mine is with AMAZON), and I create AMAZON "wish lists" so that I combine purchases to get the "free shipping" promotion. And, I want to emphasize once again, that (based upon the factors stated above) the EXTREME Option of the HP-1 has allowed me to successfully monitor the RWC (trunked, digital, simulcast) System and cure me of several years of scanner depression, lol.
