4m Slim Jim Antenna - This 4m Slim Jim Antenna is cheap and easy to build yet it greatly out performs the more usual dipole due to its low angle of radiation. An SWR of 1:1 is obtainable across the 4m ham radio FM band with a simple adjustment.

All About Ham Radio ladder-line - ladder-line is great - extremely low loss, even at high SWR. However, many hams refuse to use it because they are afflicted by common misconceptions

SWR, Impedance and Line Loss - This article deals with the practical aspects of SWR, line loss and input impedance.
