[TowerTalk] Some advice about crimp ;type coax connectors

Tue Nov 18 22:36:10 EST 2014

Weller also makes one like that.  I have one and it works great on top of
the tower, though I am trying to move toward other kinds connections up
there whenever possible.

There is one.  It's called a torch.

Here's the one I use.  (Both a torch and soldering iron).

Which brings a question to mind. Why is there not available for sale a
decent battery powered soldering iron. Sure would be nice when in the air
not to be tied to an AC power cord. I did a search (probably not very deep)
and found some battery powered irons but nothing that would deal with a few
UHF connectors out and away from the 'house'. A friend from Australia who
was in the 2-way radio business had a couple he brought when he immigrated
from Oz but I've been unable to find that they are made anymore.

Anyone have information on such a tool for use whilst up in the air??

As I stated early on, my preference is 7-16 except for price.
The Times Wire N-Type are non captive.  At the time, I couldn't find any.

I use crimp type for the same reason.  I have over 100 connectors in my
system and making crimp connections while a 10' "up there" sure beats
soldering them, particularly this time of year.
OTOH that's no longer a problem as I can no longer climb and have to pay to
have it done. Again the crimp save time and now, money. <:-))

I can't see N-type connectors as superior to UHF except for UHF and SHF and
again the 7-16 are superior.

Agree with you completely Jim.
