Dear all,
I am looking for a cheap miniature amplifier (any gain) that operates in the frequency range of 470- 890 MHz so I can add it on to a TV reception antenna that was designed to operate with a 50 ohm input impedance. Does anyone has any good recommendation?
Thanks in advance!

Normally all tv reception devices hv 75 ohm impedance. This is also applicable to tv input. Then u can easily find some tv antenna booster circuit for UHF.
If you intend to make an amplifier, you can use MMIC like MAR-8. It can be found in any SAT LNC at L-band output. These are made for 50 ohm terminations.
