Hmmmm, not my experience at all with M2. My 2MCP14 and 436CP30, along with their accessory polarization switches, and 2m and 432 egg beater antennas all met the dimensional specs and apparent operational characteristics. Robert KR7O in sales and Matt on the technical side were always very helpful and responsive to my calls and e-mails.
Sometimes you’ll find that suppliers will have antennas in stock (got all my stuff from DXEngineering, another great experience BTW) where they actually may be out of stock and simply in new production at the factory.
Guess we’ve nailed down the ends of the bell curve on experience with M2; I’ll buy from them again when I build my weak-signal arrays and probably their HF LPA as well.
Of course YMMV.
