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
