Professionell measuring by Wolf, DK1IP (Spectrumanalyser with Trackinggenerator Advantest R3361C and R&S SWR-Bridge ZRB2) gives SWR <1,04 at 15m-Aircell-7 low-loss cable for a single Yagi.

5-Element-6m-Yagi (18-Ohm-Technology) built by Manfred, DL8FBC.

Boomlength 6m, Gain 9,3dBd, Front/Rear >33dB. Bandwidth at SWR <1.5 more than 700KHz.

Above is a 7-Ele-DK7ZB for 2m.
