W3DZZ Multi-band Antenna 80-40-20-15-10m
A multiband antenna that can work from 80 to 10 meters in this illustrated docuemnt by G8ODE

Installing a Vertical Antenna Base with no Concrete
A step by step approach for a ham radio vertical antenna mount using only a hole, gravel and a piece of plumbing pipe

A Low Cost Multi Band
W3DZZ trapped multi-band antenna, exposed in this practical wireless article

The $4 special antenna
A multiband wire antenna with a twinlead feedline that can be easily tuned in several bands, witha 33 ft per leg you can have a 40 to 10 meters band coverage

Simple 20-40 m Dipole Antenna
A simple TRAP-dipole project for 20 and 40m bands includes EZNec simulations

Balloon Vertical Omni-Antennas
Experimenting vertical wire antennas for 40 and 20 meters supported by balloons resulting in excellent gain in RX and good overall performance against horizontal dipole

W3DZZ – a classic dipole heavily modified,
An easy to build multiband trapped dipole that can work well on short low bands for skip contacts

PL-259 vs Type N Connector on 430 MHz
A test and comparison of real attenuation of N-type connectors and PL-259 connectors on UHF bands, domonstrating that connectors are almost equivalent.
