antenna ampli ers (/tag/antenna-ampli er-circuits)

This car antenna ampli½er can be used up to 70 MHz and is specially designed to boost the weak signals captured by the car antenna.

It has a high input impedance and a low noise ½gure. The total gain of the car antenna ampli½er is around 30 dB and the input impedance at 30 Mhz is around 10 KΩ. The ampli½er

must be mounted directly at the base of the antenna to avoid signal losses caused by the capacitive character of the coaxial cable. This antenna amp must be used for non-mobile recievers. If you intend to install this circuit in you outdoor mounted antenna, make sure that is housed in a water proof case. Use this car antenna amp circuit only for receiver antennas. Transmitting through it will damage the components.

Efrain Drizin I’m commenting to make you be aware of what a brilliant experience my wife’s girl undergone viewing your web site. She noticed a good number of details, most notably how it is like to possess a wonderful coaching mood to let many more clearly gain knowledge of a number of tricky

matters. You truly surpassed my expected results. Thank you for distributing the productive, safe, edifying and in addition unique guidance on this topic to Jane.
