This is the link missing from my original email , the other was for the 1.125 clamps for the R25 tower

the specs are close or similar to the 1/2 CATV, but this is more flexible

There's a 75 ohm version of Times Wire LMR 600?  I've never seen an 
other than 50 ohm and I believe they'd have to change the name for a 75 
ohm version.

He made the remark "I know the LMR 600 is 75ohm so there will be a bit 
of a mismatch" which is not true.

I wonder if there isn't just a misconception here?
I have over 1500 feet of the stuff and it's all 50 ohms

Although I use the UHF connectors as well, all the ones I've seen for 
LMR-66 are quite fragile to leverage, so the coax needs to come straight 
away from the connector.  I've broken several by having them at the end 
of a loop.

>> I have about 100ft of new LMR600 and also two new UHF connectors to fit the line.   I am Feeding  a three element 6M yagi through 50ft of RG213....the end of which is about 8 ft up the side of my HG52SS tower.....What do you think of an idea I have  to use the LMR600 to feed the end of the RG213 and run directly into the shack for the K3 for 6M use.  I know the LMR 600 is 75ohm so there will be a bit of a mismatch ...will it be significant?...as far as the K3 is concerned?
