The first cable I built was using the LMR-600. It is the cable to go between the UHF antenna connector of the K-3 transceiver and the "N" INPUT connector of the amplifier. I purchased the connectors (one UHF male and one "N" male) from W5SWL on eBay. You can see a photo of the two connectors on the right. They were really inexpensive ($6.95 each) and look to be VERY well made. The Times Microwave TC-600-UMC UHF male connector for LMR-600 costs $64.95 at The Antenna Farm so these W5SWL connectors saved me a LOT of money!

The next cable to be constructed was the FSJ4-50B (1/2-inch) SuperFlex jumper from the amplifier to the LDF4-50A (1/2-inch) Heliax that runs from the shack to where it can connect to the 1-5/8-inch Heliax. I purchased a pair of Andrew F4PNMV2-HC N Male connectors on eBay that were NIB (New in Box) for $27.10 delivered.

Later, in setting up my antenna on a temporary basis, I needed to install a couple of "N" male connectors on a length of LDF4-50A and - HEY, I had the proper tool. It only took about 2-1/2 hours to install BOTH connectors and I'm proud to say they are done right! Running 1,500-watts through that cable has been flawless.
UPDATE - When I went to install the beautiful LMR-600 cable I made above, I became truly depressed! As I tried to screw the male "N" connector onto the amplifier, it seized up and would not turn. I could force it to turn with a wrench but it was effectively no longer a working connector! I am really sure I did nothing to screw up the installation of the connector, it is just that the money I saved with the W5SWL connectors turned out to be a false savings. Now I'll have to purchase a REAL Times Microwave "N" male connector and cut the bad one off then install the one I should have put on to begin with. Live and learn!
