Ladder Line or Coax For Reception only?


I have a 500 foot SkyWire Loop Antenna, about 30 feet off the ground
and I have it fed with Coax. I will only be using it to receive
Shortwave broadcasts from 2Mhz to 30Mhz. It will never be used to
transmit.


My questions are :

(1) Will using a Ladder Line instead of Coax improve my reception?

Unlikely.

(2) If so, where do I change to coax? Or do I just run the Ladder line
into the house and straight to the receiver?

This begs the question, does the receiver demand (match to) ladder
line?

(3) What about electrical interference since the ladder line isn't
shielded?

Hi Walter,

The last question raises the issue most closely associated with
positive achievement. Use coax with a 1:1 current BalUn at the
antenna feed point (or use the traditional air wound choke - same
thing but heavier/cheaper) and home noise (from any of many sources)
will be reduced IFF you suffer from this problem in the first place.
A modest home-built tuner will also go further to meeting positive
returns.
