A multiband antenna that can work from 80 to 10 meters in this illustrated docuemnt by G8ODE

A step by step approach for a ham radio vertical antenna mount using only a hole, gravel and a piece of plumbing pipe

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

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

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

An easy to build multiband trapped dipole that can work well on short low bands for skip contacts

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

Theory and origins of W4RNL Asymmetrical Hatted Vertical Dipole AHVD for portable operations.
