I will never crimp on  anything over 10 Ft above the Ground , I  have been
soldering  Connectors  for over 40 Years   But I had read how nice and
convenient   it was just  to buy some Good Crimp on tools  , Dies  ,  Coax
Cutters Etc. I spent about $ 200.00 

 

Put the Coax cutter on the LMR-400 Cable turned it a couple of Times , then
turned it Over turned it again WOW Perfect ,  Pushed it right up on the
Connecter  and crimped  it all up  Then I  attached to My comet GP-15  Tri
Band Vert  Wrapped nice Scotch tape around it  Then I climbed up in a Tree
and put ot up 70 Ft . 

 

It was cold and late in the evening But I was so excited to Hook up To My
Kenwood TS-2000 Which I did and  I had No receive but for some local strong
repeater that was in the noise.  

 

Well  about a Week later in the Cold I took it all down and found that the
Crimp on connecter the coax  had pulled out of the ant just enough to not
work ,  And I had even had a Small loop Taped at that point to keep it in . 

 

So I Just put all the fancy tools away and got a Good Amphenol Connector and
soldered it on Put it back up and Everything is still working great. 

 

Number one always use Good Connecter like Amphenol, I have made a Few Crimp
on Jumper cables but never on any Ant that I cannot reach   , I am just
sharing My experience others may have better luck, And I "am not saying I
did everything right but I do  know they were not Amphenol or good quality
connectors   , But it is not easy to climb trees and put up antennas at 63
Yrs old 

 

PS went to a Ham Fest once and a guy had Gold and Silver plated PL-259
Connectors 20 for 

$ 10.00 Dollars

 I looked to see what Brand No name on them, I always and everyone should
take time to look under the tables,  He had a Box of about 50 tarnished
Amphenol Connectors I was looking through them and He ask You like the old
dirty ones  , I said yes I could just clean them up,   He said well You can
have the whole box for $ 5.00 Dollars I  gave Him the money and Smiled all
day at the hamfest .

Thanks everyone for the input. 

I can understand the statements regarding standardizing on connectors and
cable in order to minimize tooling.

The connectors I originally purchased were not labeled in any way. They were
cheapies I specifically bought at a hamfest in order to get a little
practice in.

I will take a look at a few manufacturers and see what info I came up with.
RF Products and Amphenol come to mind first hand. I have used Amphenol in
the past for other connectors and trust their quality.

I hope you all will pardon my ignorance on this subject. I have a bit of
experience with electronics but not with cabling. Especially not with
crimped connectors. I have always soldered things in the past, but when it
came to RF connectors, I was not having much success. So I chose to take a
look into crimping.

BTW, I crimped my first TNC connector the other night and was amazed at how
easy it was in comparison to soldering a connector. 

Jeff, I will go through the archives and see what I can find. I usually have
poor luck doing searches in yahoo groups, but since you gave the date I can
most likely find it.

Thanks again for everyone's input.
