80/40 Meter Vertical Antenna
The total height of this antenna is 33 FT,the coils were make from 1/4 aluminum tubing

Antenna Vertical Links →
Full 1/4 wave vertical for 40m
To construct the antenna, I used 6 tubes of each 2m length. Starting at 10mm diameter for the top and ending with 36 mm at the foot
GAP Titan DX Evaluation
The GAP Titan DX It is appx. 25 feet high, and split in the middle with an insulator, allows to operate with acceptable SWR on every band from 80 through 10 meters, including WARC bands
Ground plane direttiva su sei direzioni
Questa e' una antenna adatta per HF se si dispone di un terreno od un cortile in cui piantare tre aste verticali di 1/4 di lunghezza

PIC-Keyer This project describes the construction of a real "QRP" keyer with a small microcontroller PIC 16F84, with slightly modified hardware also PIC16F62
RF Inductance Calculator Mean diameter of the air core coil, measured from conductor centre to conductor centre include the wire insulation thickness, if any
