I2RTF WEB page
The i2RTF cubical Quad is a evolution of usual Quad antenna
Thank to this evolution, it's allowed to obtain an rugged and light antenna,
with the very same electrical characteristics of Quad.
The 20mt. monobander is 10 pound only- 3mt. of inox. steel Ø1"3/8 mast included.
This is a not usual array, boomless -mast only - easy to assembling
The impedance adaptor, is a 93 W quarter wawe line, to obtain < 1:1.3 SWR.
Gain is 6,3 db over dipole.
Front to back ratio is 22 db
Front to side ratio is 35 db
