• Linear Loaded 40m Dipole - Dipole for 40m band. It is a simple linear loaded dipole feeded with 450-Ohm openwire feedline. Designed it for resonance at 7.050 MHz, can be tuned on 30m and 80m bands with an external antenna tuner. Build with simple electrical copper wire (2.5 mmq/13 awg) and two fishing poles with size of about 7 m/23 ft.

• Beverage Antennas - So you want to build a Beverage Antenna. This article offers insights on building a two-wire Beverage antenna for better reception. Key points include using long wire (at least a wavelength, ideally two), keeping it straight and away from vertical conductors, and sloping ends for noise reduction. The author recommends copper clad wire and mentions transformer design considerations for later discussion.

• 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. This article offers insights on building Beverage antennas for optimal reception. Key takeaways include using strong wire (copperweld or electric fence), proper termination, and a good grounding system (multiple copper rods). The author recommends maximizing antenna length and orienting it towards desired stations. For best results, utilize an antenna tuner and experiment with termination resistors.
