Antenna coupling at 915 Mhz
 

Hi,
I have recently put a cordless phone on my boat. The boat is docked
and I would like the handheld to ring when I'm on the marina.The boat
is all aluminum and limits the distance the phone base will transmit
to the handheld. The distance is down to about 1/3. If it was only
limited to 2/3 of it's normal range I wouldn't have any problem!
I would like to put an antenna outside the boat to get the range up.
Any suggestions on how to couple the signal to an external antenna?
I have a picture on abse with the subjuct "915 Mhz antenna" See the
antenna with the coil, (ignore the short one, the is a 5.8Ghz antenna)
Any chance the antenna is 50ohm and I could remove it, attach a coax
and put the antenna back on the other end? :-/

A passive repeater sounds do-able. run a coax from one antenna to the other
through the bulkhead.
