    I've been waterproofing connectors with this:

    Then I layer over it with Scotch Super 88. So far , so good.

    The advantage over butyl is that it is a lot easier to cut through and open the connector up again.

    For both work and ham activities, I've used the Ideal Industries CrimpMaster and its many different die options over 25 years. Good stuff.

    I've never understood the fascination with crimped connectors. Compression fittings seem a much better way to go.

    Coax plugs where you have to solder the braid too, eww! Who uses them? A PITA.

    When you've been soldering them (nearly 100% successfully) for almost five decades, and when speed isn't a factor, it's hard to justify changing.
    Even for someone who's not particularly dexterous, it's not difficult to solder them using basic tools. When I installed a grounding bus for six feedlines, I installed six plugs in mid-air (the plugs, not me). I later reconfigured the rotator loop above my tower, installing soldered fittings while standing on a ladder:

    It was no big deal.

    Crimp connectors are more suitable for a production environment where non-skilled personnel can quickly assemble them with minimal training.
    I have the crimp tooling and do use them but the solder/clamp types are far better IMHO.
    As for the PL259/SO239, I choose to live without them. There are far better connectors.
    Each radio gets its adaptor to N or BNC as soon as it comes in the door.

    Sure, soldering irons are cheap, but the ability to use one properly? PRICELESS!

    Properly done, crimped UHF, N, BNC and TNC connectors are superior. I buy and use the crimped braid, soldered center conductor variety. It's the best of both worlds.

    Crimped connections, done correctly, can be superior to soldered connections. A good crimped connection deforms the metal sufficiently past the yield point, but not too much, so that the "spring back" keeps the connection secure, even under thermal cycling (the coefficient of expansion of the two metals might be different) and vibration. A good crimp connection is gas-tight and won’t wick: it is sometimes referred to as a “cold weld”. Like the solder method, it can be used on solid or stranded conductors and provides a good mechanical and electrical connection.

    Having installed probably more than a couple thousand solder connectors in the last 6+ decades, I fell in love with crimp connectors. In reality you do half the work for the same connection.
