A ladder line antenna tuner for HF
I want to use my 2 x 20 m (130 Feet) dipole for all HF-bands except parts of 160 m with a 450 ohms ladder line feeder to minimize feeder losses

Antenna Feed Lines Links →
10 80m doublet antenna
is at about 57 feet 17.4m and the feeder is about 60ft 18.3m long almost vertical but comes into the house about 3 ft above ground level
How do I properly feed coax through an outside wall?
a new cable outlet to an outside wall and wanted to find out what kind of drill bit is needed to drill through and feed the coax cable
Low loss Japanese coaxial cable
about having as good an antenna system as you can manage to get the best out of six metres
Of end-feds and feed-lines
The end-fed half-wave antenna can function alone, but feed lines are the norm regardless
Openwire ladder line
Normally there is no need to retune the matchbox when using Ladder-Line
