Petlowany Three-Band Burner Antenna - The Petlowany Three-Band Burner is a simple, low-cost, trapless short vertical antenna which amazingly works on three HF bands (20, 15 and 10 meters). This web page contains pictures, performance data, and enough construction details so you can homebrew your own.

A Potpourri of 160-Meter Verticals - A potpourri of 160-Meter vertical antennas and modeling issues, inverted-L, 3-element parasitic array, 1/4-wavelength monopole

80 meters Short Dipole - The best antenna is the simple Dipole. If you have height, you even can put up a quarter wave vertical or an inverted, but sometimes you may need shorten version by 4S7NR

CobWebb multiband folded dipole - It is basically a 5 band antenna comprising of 5 full half wave dipoles for each band - between 10M & 20M, the antenna is also resonant on 6M

Dipole Calculation - Determining your proper length for the open half-wave dipole antenna

T2FD, The Forgotten Antenna - The terminated. tilted, folded dipole T2FD is a little known antenna that performs excellently. Compact in size compared to a half­-wave dipole the T2FD provides signal gain, wide frequency coverage, and exceptionally low noise characteristics.

Axial-Mode Helical Antennas - Notes on Axial-Mode Helical Antennas in Amateur Service. Helix Basics, Modeling Issues, and Short Helical Antennas Over Perfect Ground

Helical Feed Antennas - Helical antennas have long been popular in applications from VHF to microwaves requiring circular polarization, since they have the unique property of naturally providing circularly polarized radiation. Paul Wade W1GHZ

Helical/helix antenna 2.4 GHz HOWTO - Helical/helix antenna cookbook recipe for 2.4 GHz wavelans and/or WiFi applications

Skywire Loop Antenna - Also known as W0MHS Loop Skywire or Full Wave Loop Antenna, here you can find N1SU interesting observations

The 3-D Folded Loop Antenna - This article will introduce you to an antenna author call the 3-Dimensional Folded Loop. This antenna is the result of his continuing efforts to compact full-size antennas by folding and bending the elements. A one-wavelength loop that is reduced in height and width by being folded into three dimensions.

Remotely-tuned loop antenna for LW and MW - This article describes how to build a loop antenna for low frequency (LF) and medium wave (MW) reception with remote-controlled tuning. The antenna is extremely sensitive and can be built mostly from parts from old radios and tape recorders. Like all loop antennas, it is highly directional, which allows you to null out unwanted noise sources.

Optimizing half-wave sloper arrays for 160 meters - This article presents a 160-meter variation of this family of antennas and, more importantly, a discussion of the details of how to get such a beast working really well.

Short radials for ground-plane antennas - Think your elevated radials always have to be full size? N6LF lets you in on some great ideas to lessen the “wingspan” of radials, especially near the beach.

W5HN North Texas Microwave Society

European PSK Club - The European PSK Club, or EPC for short, is an informal club of amateur radio operators dedicated to maintaining high levels of amateur radio communications on PSK modes. Its purpose is to promote activity and good operating practice on the PSK modes on all amateur bands

QRPKits - Hendricks QRP Kits is a company that specializes in high quality, low cost QRP Kits

Micro908 Kit - A re-usable control & computing platform for antenna measurement, PSK31 digital modems, audio filtering, signal source & VFO, memory keyer by AMQRP

Trilithic - Broadband instruments, R and microwave components and filters, field analyzers, spectrum analyzers
