Scaletta o ladder line
La linea a scaletta o ladder line o linea bilanciata e' uno dei segreti nascosti nel felice impiego di antenne multibanda non risonanti

The Effects of VSWR on Transmitted Power
The Effects of VSWR called the Voltage Standing Wave Ratio, or VSWR, of an antenna system. There is a lot of good information available on VSWR as well as a lot misconceptions

Let's Talk Transmission Line
Modern solid state radios expect a load impedance of 50 Ω, resistive connect them to an antenna the feed-point impedance of which can be anythin

Transmission lines for dummies
450 ohm Ladder Line requires a 9:1 balun in order to match to a 50 ohm line

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
