The Importance of Shielding

TDLR version:
Shields are absolutely necessary for any radios hung on the same mast.  Homemade shields described below will work, but you might as well just buy the $28 prefab RF Armor shields for Nanostation here and Nanostation Loco here.

Longer version:
Despite better judgment, I have been rolling out some nifty homebrew "RF Armor" style shields on Nanostations and Nanostation Locos.  They yield particular benefit for any radios mounted on the same mast.  Indeed, I'd say such shields are required for co-located radios, even with 2.4GHz and 5.8GHz units.

Just earlier this week I pushed out a software upgrade to all ~50 operating WasabiNet hotspots to display a Captive Portal for users of the free wifi service.  This Captive Portal, which is very basic right now, was built in the Drupal v6 Content Management System for a couple reasons: A) I have an irrational bias towards using Drupal and B) I was able to leverage off a couple contributed Drupal modules that integrate nicely with the CooovaChilli + freeRADIUS setup I use now for managing client connections throughout
