We regularly ran 5 watts into the same antennas, and larger ones as well....42dbi's were common fare for backbone links...TWT amps, Raytheon and Lenkurt. That was the days of analog multiplex.
I did telecom microwave radios for years.
As far as part 15 stuff, who cares? Who's going to come find you and who's going to complain?
NO one! My home lan runs a 1 watt transmitter into a 10dbi vertical on one port and a 24dbi dish on another, and that's only because I haven't got the money for the export amps, or I'd be running 5 watts.

300mW (24.77dBm) + 30dBi = 54.77dBm EIRP.
The maximum tx power you can *legally* run with 30dBi of antenna gain PTP is
30 - (30 - 6) / 3 = 22dBm, or 158.49mW.
In other words, you're about 2X (3dBm) too high in tx power.

Yes, they're good, and deliver plenty gain, just make dammed sure they're fastened to a SOLID structure, the pattern is very tight. They're heavy. You will want to inspect them regularly for mounting bracket tightness. I lost a mounting bracket in the snow one winter when it came loose. The wind beat the snot out of the dish before I could get up to make repairs. I shot 53 miles with a pair from a 535' building in a downtown to a mountain top with them with 300mw in commercial service. They're big, they wind-load like hell, and they collect ice, and wind makes them sing, causing a lot of vibration. I double nut every bolt. They're a knock off of the Prodlin (I think thats the spelling) dishes from the 1980's. Good stuff.

2.4 GHz 30 dBi High Performance Reflector Grid Antenna Model: HG2430D
If so, got any real stats on em?
Thanks.. C.
