[HomeBrew] A method for wireless CATV

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?
