Antennas for 17 meters Links

17 Meter Wire Antennas
12m e' un normale dipolo, sui 17m funziona come un dipolo caricato

Build a 17 Meter Reduced Size Coaxial Moxon Retangle
A standard Moxon rectangle designed for 17 meters would be about 19 3/4 feet wide, the same Moxon retangle is reduced to about 11 feet wide

Builda 12/17 Meter Trap Dipole
Build a for 12 - 17 meter Dipole rotatable with traps

Dual-band-wire-beam-12-and-17mt
the dual band wire Beam Moxon with Fiberglass tubing spreaders, Flexweave elements 12/17 m Moxon with one 50 ohm feed

18 MHz 3element Beam
Its a 28 Ohm version on a 5m boom with 5.7


Linear-loaded-short-dipole-21mhz

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

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

A simple SWR Meter is to be used at HF

A simple SWR Meter is to be used at HF An SWR meter provides information about how well matched is your antenna with the transmitter and how well power is being radiated
