>How do you re-use UHF male connectors with a total of 5 solder points ??

 I have been doing it for 40+ years.

I use a full sized propane torch with a `pencil flame' tip.

I stand it on the work bench with the flame facing away from me.

I cut the coax 2" from the back of the connector, I set the shell off.

I handle the coax with `house hold' pliers.

I heat the tip with the connector facing away from me, when the solder
runs, I sling the solder into the trash can between me and the bench.

I inspect and cool, rotate if required and re-heat remaining solder
and re-sling.  If required I make sure the wire is free with a jewelers
screw driver.

I heat one side hole at a time, I carefully bounce the connector
onto the work bench (on to a piece of old 2 by 4) on it's side and
the negative acceleration slings the solder onto the board, still
holding the coax with the pliers.

After all 4 holes are cleared I heat all 4 holes and I grip the
`reeded' end (the end just before the center pin) with another
pair of pliers (set to be the big size) and I unscrew the coax out
of the connector, quickly I sling the opened end into the trash can
with the coax. (or against the board)

I use my pocket knife and small hand tools to scrape and de-burr as
required.

I inspect then I put the shell back on and I put it into the box.
(of connectors)  If I have a clean connector, I use it rather than
using a new one.  I wait until I have half a dozen to clean before
I do them.  I so not use a used phenolic insulated connector for UHF,
I use a used or new teflon insulated connector.  Because of the
possibility of absorbing moisture by the phenolic insulator.

  If you have any questions ask.
