TV UHF aerial amplifier - PCB EPS 80022

The radio-active topic

Postby bill the farmer » Sat Jun 18, 2011 12:00 am

I have a very old TV aerial amplifier that I built from an article in an old Elector magazine and never used. The PCB features a BFT66 FET/transistor, two trimmers, a half turn coil, two inductors made with ferrite beads, three ceramic capacitors, two tantalum capacitors, and four resistors. and a voltage regulator.

The PCB has the number EPS.80022 on both sides.

Is it possible to identify the original article? I noticed a reference to the Elector Item Tracer in a similar post, but could not find anything on this site.

Regards
Bill

EPS.80022 circuit board was used in the Aerial Booster project, which featured in Elektor February 1980 pages 4 to 8.

The basic wideband amplifier had a bandwidth from 80 to 800 MHz. An input filter (with suitable values of L1, C6, C7, C8) could be added to narrow the bandwidth to a specific frequency band.

When I dug out my old stuff found two of these PCB's. But unfortunately the old Elektor issues I had became a mushy pile of paper pulp during a flood we had the year before. Can someone help me with the schematics?

Back articles all the way back to issue # 1 are supplied by kind ladies called Cindy and Jolanda at Elektor customer services. Write them an equally kind email, they are at

stating exact article title, year of publication and PCB number.
