The having no port is the main problem...That means you
have to use those coupler devices that fit behind the antenna
in the phone...Unfortunately, I just had to buy a new phone,
and my new one is the same way. No port...They make a sleeve
that fits over the top, and has a patch to couple to the internal
antenna, but I have to wonder how well it works...Some reports
seem lackluster...As far as antennas, I guess it depends on
what you want...A connection to a cheap UHF TV antenna
might work ok....But most long distance house cell antennas
are yagi's that I see sold. Anything commonly used for UHF,
could be adapted to cell phone...Often on those freq's, just
moving a few feet can make a big difference...So I'd try different
locations, and try to find "hot spots"...Thats about where I would
mount the antenna if it's not going to be real high...
I'd like to find the goofball that decided these phones don't
need an antenna port.... Whatta putz....Having an outside
antenna makes a huge difference out on the interstates... MK
