5-Element-18-Ohm-Yagi with 6m-Boom
Short data: Gain 9.3dBd, very good F/R >33dB, bandwidth 700KHz (49.8-50.5 MHz) at SWR < 1.5
 |
This Yagi has slightly less gain than the 12,5-Ohm-Yagi, but is not so critical and the pattern is excellent. You can mount the antenna 1,50m above a roof or 2m above other Yagis for shortwave. The Photo shows the Yagi built by Manfred, DL8FBC. On the top is a 7-Ele-DK7ZB-Yagi for the 2m-band. |

Match with 2xLambda/4 60-Ohm-coax in parallel to a grounded socket, feedpoint impedance 50Ohm. You can built up a Gamma-Match, if you don't have 60-Ohm-coax!
