If you want monoband this is a good option

I used it before with the CATV on my 6m yagi @ 145ft before change it to 7/8
heliax, the run is 250ft, the swr was around 1.2:1
there are a lot of information how to make the connectors from copper pipes or
other options.

Subject: [TowerTalk] 75ohm cable
I am the proud recipent of numerous rolls of 75 ohm, 1/2 in CATV cable. Since
all of my antennas require 250ft or mor runs this is a real blessing. I have a
few questions before I start replacing the RG 213.
1. All of my yagis are 50 ohm, fed through rf chokes to the feed point. Can I
just connect the 75 ohm and not worry about the small mismatch or do I need to
use some type of matching network?
2. Are there commercial matching networks to do the job I want that will handle
1.5kw?
3. I have several articles that allow me to make PL-259's to fit this coax. Is
there an easier way?
thanks, Carol
