High Gain UHF Booster
Re: High Gain UHF Booster
Please tell me Another circuit
Re: High Gain UHF Booster
The one added by Magneto is the best and the most commonly used one. Can you put some photos of the circuit board you made. Would like to have top and bottom view clearly. Without these, we can't trust that you made the right thing (or even made it at all ).
This is another one.
This is an UHF band TV antenna preamplifier circuit With 15dB gain to build easily. It is formed based on BF180 UHF Transistor. The first stage is an band pass filter constructed by the C1, CV1, L1, L4, C7 and C3, the second stage is a base-common voltage amplifier with low input impedance to match. Build the L1 ~ L4 as air core coil to obtain high Q-Factor.
After assembling, pack it into a proper metallic box and connect the ground of the circuit to the box to reduce noise effect.

I didn't make it. But I tried a booster that i Bought from the market. When I have time i will Build that circuit.
Thanks

Re: High Gain UHF Booster
Because I want to Know a Powerful Booster

You didn't even build the first one.. do you think it is fair to ask another even without building the first one? What exactly you want to get yourself satisfied, a whole lot of circuit diagrams on your table?Nipuna wrote:Because I want to Know a Powerful Booster
