Not only are the food not on the shelves, and other shortages, but even Ham radio! HF Antennas! I wanted to order HF Hex Beam, backed order due to delivery issues..(All suppliers) Has anyone else experiencing the same issues... DE NN2X
A Hexbeam is a nice antenna. In the meantime, are you in a location where you could build your own monoband yagi?
If price isn't a consideration, these appear to be available. https://www.vhqhex.com/ Or build one yourself: https://mgs4u.com/hexbeam-antenna-parts/ MGS does note that grey spreaders are on backorder. I'm sure someone will have center posts available for parts.
Actually, I am working on it...I did have some MGS Spreaders handy (Bought earlier this year). I also have a 42 FT Aluminum Telescopic mast... When down to HomeDepot, and got a few parts, and have the driven element (20 Meters) all assembled, tomorrow I will raise up to 36 ft..(Just as a rotatable Dipole). Check VSWR all good! I had one of those common mode chokes and slapped all together...All fun...Next week, I will put the reflector together next weekend..This is most of the fun! Cheers DE NN2X
