Quite funny and nice offer...

I just finish and succeed to install/fit a PL-259 connector on this type of CATV heliax using plumbing adaptor compression fittings. The 
second step is to try to have them installled on our 52 ohms devices... If you already tested theses cable and found an easy and simple way 
to have them match 52 ohms you will save us a lot of work.

What i want to do is the to have each length adjusted "CUT" for 1/2 wave length at a specific frequency. I'm guessing it will not be too 
hard on HF but could be a bit tricky on 1.2ghz? eg: How far from each cut frequency the cable will retain this 52 ohms matching? 

I have about more that 500 feets coming from my and neighbourgs back yards when the CATV installers wants to put theses old lines in their 
scrap container.

Debate is open!

P.S. If you see them around your back yards just ask them and offer them to rolled up the line they are just cutting. They will be more 
than happy to let you take them it is some work they will not have to do. You can have some other extra roll already made by them if you 
have the right timing as they change them at 10 years intervall or when the technology evolution demands it.
