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!
