Re: [PLUG] Public Service Announcement (Really)
|
you would love to see the access i get even out here in NJ with a

Ebay $225 and it works well
Consequently I have one in our own cage in 401 simply to allow me to
test out of network into our network and it grabs a signal very very
well
(actually thats a moto canopy )
