My architect neighbour was at Tandy and picked up a
Panasonic KT-TG2501ALS 2.4Ghz digital cordless
phone. Now he is hoping to put the base station in
his office on the main street, and pick up calls at night
with the handset, from his apartment up the hill.
The range from his second floor office to his apartment
about 40 metres up on the hillside is about 200-300 metres
(we can check a town plan to get a better measurement
if that is critical). There is line of sight from most of the
balcony down to a rooftop area adjoining his office. We
have checked that with the cordless phone base in his
office, he can pick up a call if he is standing at the front
of his balcony. However if he move backs very far (the
balcony is only 2 metres deep) or is inside, he doesn't get
The office has a couple of walls, the end one with steel
reinforcing, and there would be a metal roof in the way,
so I'm guessing the cordless phone signal is leaking out
of one of the windowed walls, which just misses having
line of sight to the apartment.
He asked me about extending the cordless base station
antenna about five metres through the wall, to a position
where there is a clear line of sight. I have to admit I'm
fairly dubious about how effective running a length of
coax would be for a 2.4 GHz phone .
Do any of these sorts of phones actually come with an
external antenna with an optional long coax? I couldn't
find any when I searched.
An alternative I thought about was to stick the base station
itself out in the open. I'd have to run a phone extention, and
a low voltage plugpack line, and bring back the phone charge
socket inside (the base unit apparently changes the phone
security code each time it is charged, which is why I figure
I have to bring those two lines back).
The base station would have to be in a waterproof container
if I put it outside. Any suggestions as to whether I should
favour glass, or plastic or ?
Oh yes, and the bonus question, how well do these cordless
phones work on a dark and stormy night? We are heading into
the rainy season, and if it is going to fail to connect every
time a rain squall passes through, that could be a problem.
Any suggestions about alternatives? I figure someone doing
home automation has had similar needs from a phone, and
found a solution.
