Are all forms of Ham communications on 5.2 & 5.4 limited to 1W eirp or
only high-speed data/video?Short answer: Max achievable EIRP is 946.4
Kilo-watts for Part 97, or obviously the minimum necessary to carry
out the communications, just like any other thing in ham radio.Nothing
overlaps at 5.2 GHz... more so 5.6 & 5.7 see these

Awesome resource, thanks!
These were VERY amusing to read, especially the EIRP!
900 MHz (non spread spectrum i.e 802.11g) 1500 watts (per 97.313) 14
dBd yagi 37.8 Kilo-watts
What sort of surplus amplifier hardware is available for
900MHz and at what sort of prices, please? I hate to
think of the price tag on a 1.5KW 900MHz amp!
2.4 GHz (non spread spectrum i.e. 802.11g) 1500 watts (per 97.313)
24 dBi partial parabolic 376.8 Kilo-watts
Generating 1.5KW on 2.4GHz is not within the reach of the
average Ham, even 150W may be tough, though that still
equals 37.7KW EIRP! :-)
The 3.3GHz transverter http://www.ubnt.com/sr3_faq.php4
is interesting for many reasons:
1. It interfaces with the Atheros Linux MadWiFi driver.
2. It takes a consumer off-the-shelf 2.4 GHz 802.11 hardware
and puts it on the 3.3GHz Ham band.
3. 100W x 25 dBi dish = 31.6 Kilo-watts EIRP!!
Questions:
1. What is this device likely to cost?
2. Are amplifiers available surplus and what are
they likely to cost?
3. Same question re. high gain 3.3GHz antennas and the
associated cables/waveguides?
4. Distance and signal toleration in bad weather?
It is so much fun to learn new things in Ham radio!
