Window Line Connectors... ???
 

Convenient (non-weatherproof) connectors are available for humble,
TV-style, 300 Ohm twinlead. But I am not aware of any sort of
connectors for 450 Ohm window line.

Does anyone in this NG know of any such connector? If yes, where
can they be purchased? And if not, how about clever work-arounds--
perhaps doing something with banana plugs?

Thanks and 73,

Ed

I use the Radio Shack banana plugs. They're heavy duty. Have a male
plug at one end, a female jack at the other end. Attach the ladderline
wire with the built-in thumb screws. The double banana RS connectors
are the same width as 450 ohm ladderline. As I understand, they're
patterned after the old General Radio banana plugs, which are no
longer available.

See part 278-308 at the RS site.

The Pomona MDP series is similar, but uses an internal setscrew rather
than a thumbscrew. Digi-Key sells the Pomona plugs with nickel-plated
brass contacts for $2.47 in onesies, quite a bit less than the $6.29
gold-plated Radio Shack versions. Pomona does make gold-plated models
but Digi-Key doesn't carry them.

I use banana plugs and they work great. You can even
get them spaced approximately for 450 ohm line.

Hi Bob -

Thanks for your comments! It seems the NG verdict is
that banana plugs are the preferred work-around for the
missing connectors.

are those bannaplugs in anyway weatherproof?? i'd guess they'd get
corroded pretty quick and pretty bad no??

Well, I live on the norther California coast about ½-mile from the
ocean and have used them for over ten years at this location with on
corrosion problems whatsoever.

A good alternative - if you can find them - are the Belling-Lee "O-Z"
banana plugs, available in 3mm and 4mm diameters.

For data, see http://uk.farnell.com (no "www") and enter 317147 in the
Search box. Under "Tech Info" you can click the little page icon to see
a PDF data sheet.

The data sheet doesn't say so, but they are silver-plated. I've used
them outside for years, with no noticeable corrosion. Also the Z-shaped
spring in the plug is very easy to re-tension with a thumbnail.
