Why terminate a Beverages - Terminating the far end of the Beverage makes it unidirectional. It also makes the receiving angle of the antenna lower.

Poor ground, better Beverage - Poorer conducting earth beneath a Beverage gives better performance

Beverage Antenna Construction - Types of beverage wires, choose best supports and insulators, multiple antennas at one feedpoint, all well documented with photos and exaustive explanation.

Beverages: How Short Can They Be - When we think of Beverage antennas, we automatically think of several acres of land and lots of wire!

Transmission Lines - Whenever you choose a coax feedline, the frequency of operation is a very important consideration. Over the operating bandwidth of the coax the VSWR is low, typically 1.2:1 or better. Insertion loss is also an important parameter. It is usually specified in dB/foot and is a linear relationship.

Construction Practices - The construction of light weight structures that support wire antennas requires some definite insight into the behavior of the materials

Yagi Element Mounting Considerations - One of the most important considerations when designing and building a Yagi antenna is the method used to attach the elements to a boom. This is true because the boom influences the electrical length of the elements. In this article JH Reisert explain with drawings techniques on mounting yagi antenna elements to a boom

A Magnetic Loop antenna for 7-21 mhz - If you find external wire antennas obtrusive for amateur radio or short wave listening, then this is the antenna for you, is just 1 meter diameter
