Wanting to watch CATV on the screened in back porch (where running a cable
extension line would have been very difficult)...I connected the cable box
output to a 3 stage class A amplifier chain (e.g. 2N5179 / 2N5179 / 2N5109
I built w/ muliiple feedback at about 25 dB gain per stage) and the output
to a channel 3 (i.e. 62MHz) dipole. Then w/ a TV set on the porch tuned to
channel 3...I was able to receive wireless CATV.
Not knowing the output level from the cable box.....I was lucky and obtained
about a 100' wireless range.
Looking for any additional ideas on how I might refine this idea further.
For example, on further thought....I assume that the cable box output is FM
and I could have built an amplifier chain using class C stages (and used
fewer parts and power supply).....however, have no idea on the output level
provided by a cable box...so it might not be able to initially turn on a
class C amplifier).
Comments / other ideas?
