Happy New Year,
Another option may be WA5VJB's 23cm 'Easy Yagi' design.
This is lightweight, disposible and costs next to nothing to build, whilst having a good 'power to weight' ratio! It is one in the series yagis designed by Kent and extremely popular in the USA.
I need to check where the design has been recently published . I'm not sure that it's on Kent's web page yet. I think it has appeared in CQ VHF.
I would dearly love to receive some reports on the 23cm (and up) activities of the SOTA enthusiasts for the RSGB RADCOM GHz Bands column, please?
