MARTIN G8JNJ Active antennas Kent Britain, WA5VJB, suggested that I could further simplify my active antenna circuit, by omitting the complicated DC injection and regulator circuit and replacing it with a resistive load. I took his advice and modified the output attenuator circuit to act as a load resistor and voltage dropper, as shown below. Amplifier Circuit Design Amplifier Project Scheme Diagram This is the circuit diagram of active antenna amplifier for FM radio device. With only a small handfull of parts you can built this trusty FM Amplifier to boost the signal from the radio transmitter. The circuit works with only 1 UHF VHF type transistor, MFE201. This amplifier will pull in all distant FM stations clearly. Active Antenna Circuit Diagram Learning Electronics The active antenna is readily constructed with the aid of the two printed circuit boards shown. Since we are concerned with only relatively low radio frequencies, the choice of components is not too crucial. Various types of FET may be used: BF245, BF246, BF256, or the SMD variants of these, but do mind their connections! Active Antenna Electronic Circuits This "Active Antenna" is cheap to build" and has a range of 1 to 30Mhz at between 14 and 20dB gain __ Designed by Tony van Roon & Rodney A. Kreuter. Active Antenna for HF VHF UHF This simple little circuit can be used for AM, FM, and Shortwave (SW).

Of course, good RF param eters must be achieved. An IL of less than 0.5 dB is expected. The isolation must be better than 65 dB and the SWR lower than 1.40. My design solu tion was analyzed and optimized by using the SUPER COMPACT pro gram.1 Circuit Description The full schematic diagram of the circuit is shown in Fig 2. The lengths Radio & RF Circuits Circuit Diagram This circuit is so small and one can easily fit it in a match box. This circuit generates a small RF power on 27 MHz band. But the out put power is strong enough for hearing on any 27 MHz band receiver in a building. If you want to use the circuit on only one frequency then remove the socket of crystal and directly solder the crystal. Active antenna circuit diagram Electroniq.net An very simple and useful active antenna can be constructed using this electronic circuit diagram . This active antenna is based on transistors and other few common components . Because in practice of frequency short wave reception, the general rule is that if the used antenna is longer , the stronger the received signal will be we need in some cases ( when we can not built a Antenna Detecting Reference Design V1 Usually, GPS modules from SIM have reserved a supply VCC_RF for active antenna, customers can confirm the voltage in HD document, if the VCC_RF match with the active antenna (see antenna datasheet to confirm), and then the following diagram is the typical circuit.
