9-Element-28-Ohm-Yagi with 14m-Boom
Short data: Gain 12.34 dBd (14.49dBi), F/B 34dB, bandwidth 1MHz (49.4-50.45 MHz) at SWR < 1.5
Excellent pattern, bandwidth and gain. I used this Yagi for 2 years with very good results.
These data will not be reached by any comparable known Yagi, the first choice for 6m-EME and severe DX!
The 4x9-El.-28-Ohm-Yagi group
of Jarda, OK1RD
The Yagi built by Roman, SP2DDX
The 9-Ele.-Yagi combined with a 4-El.-Stepp-IR
A real big gun!!
Antenna built by
Jacques has redesigned the Yagi for 14mm-elements.
How the antenna is working you see on the HP-Analyzer-Plot left.
