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

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.
