The Array Solutions AS-75:50-1 should match the impedance of your CATV cable
to the rest of your antenna system.

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
