Back in the day we were all warned not to use ac line cord for antenna feeds.
Now with modern plastics/pvc maybe things have changed??

I started off by using Belden 72 ohm KW twin lead for receive hoping to see what made the Dallas Lankford " quiet antennas " work ..

Things were looking good till I ran out of the Belden twin lead and they don't make it any more..

Decided to try " Install Link " from Amazon for low money.. 38 bux for 250 feet..

Worked great quality for DC interconnects so it was time to measure Z and see if this line would be good for remote receive antennas..

Good news for 630m and lower...

100 ft. of this terminated line measures 104 ohms Z, good..

Freq      Loss
11mhz - 5.57db
4mhz. - 3.27db
1.8mhz. - 2.39db
475kc. - .69db
136kc. - .18db
17.2kc. - .16db

Of course a remote LNA at the antenna makes the loss go away..

Am using this now for verticals and loops..

The possibilities are endless...  Phased arrays??
