Remote Control I.R. Extender (Pyramid)

Re: Extending range of:  (Pyramid) WIRELESS
REMOTE CONTROL EXTENDER. I use these to
remotely control a cable box, but one of the
extenders (transitter) is too far away to
work properly. How can I boost the power
output of the transmitter or increase the
sensitivity of the pyramid receiver?

1. Position the one you aim the remote at
(the RF transmitter), as high as possible.
2. Try adding more antenna length by
wrapping a few turns of about 18" of bare
copper wire to the top of the antenna. Try
same for the RF receiver side.
3. Try adding a passive repeater, if RF is
passing through multiple floors or walls. A
passive repeater is a "pick-up" antenna in
the room with the RF transmitter, coupled by
coax to a retransmitting antenna near the RF
receiver...yes this sort of negates the
entire concept of the "extender" but I used
it to couple signal from second floor to
basement. I used RG-58 with shield and foil
stripped back about two feet at each end. I
dropped the coax down a return air duct to
the basment and positioned the unshielded
portion near the room with the piramid RF
receiver. Worked well.
