I have almost 100% Tranzeo CPEs and almost any CPQ and SL2 can do 20 10 or 5Mhz 
channels with the new 4.0.5 Firm.  

5 and 10Mhz has really helped in some noisy areas.  I had one tower I was about 
to take the sectors down and once going to 5mhz I have 15 new clients.

Smaller channel sizes is one thing we haven't done yet, but we can'd do it
permanently unless we swap out a few CPE's.  Have a couple of older
Tranzeo's and an older Deliberant or two that don't support smaller channel
sizes. 

Appreciate the info and help.  We are going to try it on the Test AP we have
up to see if it makes a difference on the couple of clients we have on there
right now.

I have a lot of Deliberant CPE in my network, just a few of their 
APS.  But the newer generation stock with Atheros cards supports 
20/10/5 MHz channels.

 From their site, concerning the Duos:

Product contains:
    * Dual-Radio with adjustable RF Output Power
    * Rugged cast aluminum hinged enclosure
    * Full, half, and quarter bandwidth channels
    * Multi-BSSID support (VSSID) with VLAN tags
    * PoE built-in for single cable installation
    * Configurable Multi-mode AP
        * AP mode/AP client mode
        * WDS
        * AP router/AP client router
        * AP repeater
        * Redundant PtP bridge with STP
