K3KY's Short Beverage  ^pop - Originally planned as an 80/160 Beverage, this antenna is a terrific performer on 40 and 30 meters

Ground System on a 160M vertical - Ground system measurements on a 160 M vertical by Rudy Severns N6LF

A Lowband Antenna that is Almost Free  ^pop - The Shunt-fed Tower, an effective Low Band Antenna, uses your beam as a capacitive top-hat and only needs a simple feed network and a good ground system to work DX on 80M and 160M.

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.

How to make an end-fed antenna work  ^pop - Here is a sure fire way to make end-fed halfwave antennas fed with a 50 ohm coupler work - without long radials, grounds, chokes, voodoo.

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.

Mobile Helix Antennas for HF - Normal mode helix antennas for HF mobile. Photos andn plan for a 20 meters mobile helix antenna by N2MH

Antenna Modelling - Antenna modelling notes, including wich antenna modelling software choose and where to find useful resources for antenna planning and home-brewing.

Copper J-Pole Antennas - Conejo Valley Amateur Radio Club, article edited by Rory Eikland, KG6HCU and Ken Larson, KJ6RZ, they have had excellent experience building and using J-Pole antennas, and share their experience on planning VHF and UHF Jpole antennas.

Long Loopstick Antenna - Wound on a 3 foot length of PVC pipe, the long loopstick antenna was an experiment to try to improve AM radio reception without using a long wire or ground.

Amateur Radio Antennas: Ground Theory - Perfect ground vs. poor ground. What is the difference? How does the ground influence the DX-gain?

Groundplane antenna - Short guide to build your own groundplane antenna, includes radial measurements fro warc bands

Half square antenna - The elevated half square antenna is a very simple antenna that can be constructed from common materials yet gives significant improvement over a dipole at the same elevation. Ground mounted versions of this antenna are commonly used in amateur radio for 75/80 and 160 meter bands

Home Planet Release 3.1 - Comprehensive astronomy / space / satellite-tracking package for Microsoft Windows 95/98/Me and Windows NT 4.0/2000/XP

Grounding Concepts - What is ground?RF ground and the ground plane, how can I tell if I have a good ground? ground loops

Why grounding - Overvoltage protection, Voltage stabilization, Grounding in wiring, Ground wire resistance

Ground Problems - RF ground systems

Station Lightning Protection - This website outlays the basic knowledge, safe design and installed equipment that are employed in the lightning protection system of a US Coast Guard Auxiliary Radio Facility. This should also be relevant to the Civil Air Patrol, MARS, and Amateur Radio stations who provide emergency communications capability for public safety or the military
