The Kite and Balloon Antenna
One of the easiest to deploy transmit antennas that coincidentally I have become fond of consists of the mast at 12 metres, a small 4 metre fibreglass stub on the top, and about a quarter wave (40 metres) of wire on the top of that. I call it the Protracted L . The wire is supported by one or two Helikites depending on the wind speed

A Practical Antenna for 160 Metres
It consists of 140 feet of insulated wire, the first half of which 70 feet is space wound on an insulated tube. I used glass fibre tubing which was to hand, but PVC
A Stealthy HF Coat Hanger Antenna
In fact, there's nothing new on this page. It's just about a very common HF antenna that I recently built
Antenna per trasmissione Inverted L
Questa e' stata la mia prima antenna per i 160 metri, in uso dal 1986 al 1990, quando ero ancora attivo su tutte le bande
Vertical for 160 meter
Vertical for 160 meter by SP7QHP
Antenna verticale per i 160 metri
La lunghezza dell'antenna si e ridotta in totale a 8 metri e 80 cm,ovvero circa 22% del quarto d'onda lineare. La bobina di compensazione e stata fissata a circa 32% di altezza dalla base

Linear loaded short dipole 21Mhz For my amateur radio activities on the HF bands I only have a 3.6 m wide balcony available for antennas. After some study I decided to experiment with a shortened dipole for the 15 m band
Rx antennas 4Square Rx Vertical Array My frequency design of 1.825 MHz a 90 degrees line would be 33,70 metersinstead of the previously calculated 33,27 m
Atu balanced feeder antenna system An ATU has the advantage of bringing the feeder-antenna system to resonance, act as a band pass filter both on receive and transmit and a low SWR
