2m big wheel antenna

For several years now I have been using a big-wheel horizontal omni-directional antenna. This has a few dB of gain and does not need a rotator.

With 2.5W SSB it regularly gets me 200km in the Tuesday evening UKAC activity contests organised by the RSGB. On FT8 my QRP CQs are regularly copied in Cornwall under flat conditions. Most days, I spot stations in 7 countries by aircraft reflection on 2m FT8. What surprised me was it is quite effective on 70cm SSB. Most sessions my 70cm QRP is copied over 100km.
