I've been reading this thread about "which connector is best?" with some
degree of interest. I must agree with Tom, W8JI. It isn't so much whose
name is on the bag the connector comes in---it's how you do the prep and
Recipe for a solid connection to your PL-259 or SO-239 etc.---
1. If u can buy the silver plated/teflon PL-259's, or silver with gold
pins for a decent price (like from The Wireman, or Cable X-Perts etc.),
you're off to a great start.
2. Whatever connector you're soldering---clean off the oil slick they are
all coated in. I use simple DAWN dish soap and water, then dry.
3. Abraid the surface lightly surrounding each hole and run a narrow strip
of black (water proof type) sandpaper thru the pin. (I actually have a
very nice precision rat tail file for this.) You can abrade the holes with
black sandpaper, or a few light swipes with a file. It's amazing how much
this helps the connector take solder.
4. Finally: use heat! Fast heat! on 60/40 Rosin Core solder. The "Solder
Torch" works great/fantastic for this--but any 175 watt-250 watt gun or
iron works fine (just keep the tip cleaned and tinned with that potted
material, radio shack sells it in tiny cans/part #64-020/much cheaper at
wholesale electric houses-various names). If you use slower--lower powered
guns---you'll melt ur coax jacket, and possibly your dielectric as well,
besides getting ugly/poor solder connections.
So good luck with your connector soldering. Connectors are one of the most
significant sources of loss and other problems (RFI, TVI, spurious signal
radiation) in any antenna system. Proper connector preparation and
attachment is well worth the extra investment in time and money to make
sure we get it right!
73 es hope to hear u all this weekend!
