The
BeeLine Transmitter solves one of the biggest problems encountered while using
other types of low power transmitter beacons, the frequency is user programmable!
You no
longer have to wonder who else is using 433.92Mhz, because you can
program your beacon to any frequency you choose within the 70cm ham radio
band. Click for a picture showing the
assembled transmitter with antenna.
It's
also very economical. No need for a dedicated receiver; use your FM
scanner or hand-held ham radio! Add an
easy
to build Yagi antenna, and you're in business for a
fraction of the cost of
other systems.
Coupled
with a lithium-poly battery lasting more than 48 hours, the entire unit weighs just 30 grams (1
oz). and fits inside a 29mm coupler tube (id= 1.14"). Even though a specialized charger is required,
you will realize
a cost savings after just a few flights vs. using expendable (and heavy)
9V alkaline batteries.
When
assembled, the battery fits behind the transmitter, and the entire board is
wrapped in protective heat shrink. The 1/4 wave whip antenna is 6.25"
long.
