Marlon,
What would you suggest? I am afraid of proprietary stuff because I
don't know enough industry history to understand the players.

Hiya Jason,
Why not just buy ISP grade product? Then you don't have to worry
about all of this.
AND at 2.4 the CLIENT side isn't limited to 36 dB. It starts there
with a 30 dB radio with a 6 dB antenna. For every one db of radio tx
dB you drop you can go up 3 dB of antenna gain.

Subject: [WISPA] Legal Radio and Antenna Combos - Are there any in
existance?
Everyone,
I am at my wits end. I have searched high and low for a mini-pci
radio & sector antenna combo for an 802.11b AP that are legal under
the current FCC rules, which by my interpretation are:
1. Total output is 36 dbm or less.
2. Antenna characteristics must be the same as an antenna that has
been approved for use with that radio, where TYPE refers to antennas
with SIMILAR in and out of band radiation patterns.
3. Antenna gain must be equal to or less than the maximum the radio
has been approved to work with.
I can NOT find a radio that is approved for any antenna with real
gain. I don't want to mind just the SPIRIT of the law, but the law
itself.
What combos are you other guys who like building your own system. I
want to put together a Mikrotik with 3 radios and sectors for an AP.
The sectors I am looking at are:
Antenna Gain Width Pol
WRW2400-VF/A/H 13dbi 120 H

I am sorry if this table doesn't wrap well on some email clients.
I am still looking for a 18 dbi HZ pol antenna with FCC certs because
I think it can be used with a DT-RWZ-200mW-WC, although it is pcmcia
and I'll have to figure out how to use it with a 500 series RB (Note,
there are foreign antennas that have 18 dbi, but don't come with FCC
certs; see my last post). As far as I can tell, the CM9's can't be
used anywhere.
Ideally, I would like to use the 22 dbi Teletronics in my application
with a 14dbm radio for the greatest receive gain. Or at least a HZ
polarized antenna with decent gain.
Anyway, can someone please help. I appreciate those of you who have
helped me to even reach this point.
