I would love to see an omnitik in 2.4Ghz. I am currently using the 751u but I have industrial environments and the omnitik is a better fit (if it was 2.4Ghz). Also, I would love to have the omnitiks antennas over the 751u. High output power in the 751u is useless to me with such low gain antennas.
the groove doesn't have a built in switch. I could use an omnitik 2.4Ghz as a soho router in my industrial environments with high gain dual polarity antennas.
I can put something together to do this but I would need a 493 + enclosure + wireless card + 2 antennas which is easily $238. Additionally, the OmniTIK is designed to mount to just about anything quickly and easily where a metal boxed 493 would be a little more effort and still wouldn't be as tough.
The OmniTIK 5Ghz is $89, so if a 2.4Ghz was similar the savings would be quite good.
I would also add that an OmniTIK is auto-WDS and HWMP+ in 2.4Ghz would make a nice little mesh node too.
