Liquid Metal Antenna - Liquid metal antenna using galinstan by Mike Lake KD8CIK

Vertical antenna for 160 meter - This high antenna require a large ground composed by 40 radials. It's not very handy expecially in windy situations but is very powerfull in pile-ups. In italian

7Mhz Vertical antenna  ^pop - The secret with this antenna is to install as many radials as you can around the base of the antenna, they can be anything from 1/8 wave or longer.

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.

Rotating Tower Systems - Using our components you can build a rotating tower with greater capability than 3-4 static towers. A rotating tower allows common rotation of HF stacked arrays, VHF and UHF arrays, and antennas mounted at optimum heights. Component design also allows tower shunt loading and end support for wire antennas
