The small magnetic loop has received growing interestas a relatively efficient compact high frequency antennaforlimited spaces. These antennas feature aradiatingconductor in a loop of either circular orpolygon shape of a circumference between 0.1λ and 0.25λresonated to theoperating frequency with ...

For reference, the AIS-catcher default decoder showed roughly a 30% improvement over a FM-based decoder in message count. An important factor of the high message rate at the Meteotoren though seems to stem from the location and the installed Yagi antenna. An experiment where we reran with a...
The reading device creates a high frequency field such as a gate that acts on the antenna of the transponder. Voltage is induced in the antenna; the chip is activated and creates an individual response by field attenuation. The response is received by the reader. Planar Coil in a RFID Trans...
17 Receiver circuits schematic: 18 MPU/Transmitter/Front panel schematic: 19 How it works: Signals from the antenna first pass through the transmitters Low Pass Filter, which are selected for the current operating band by two relays, RY1 and RY2. The receiver signal is picked off from the ...
HF radars designed for skywave operations selectively illuminate an area of the Earth’s surface by means of the choice of radar frequency, governed by the transmitting antenna design and the prevailing electron density distribution in the ionosphere. Any HF radar transmission has the potential to ...
(LNA) to compensate for the coupling losses of each helical antenna across a wide frequency range. Although there is a mismatch loss at 25 MHz between the 50 Ω impedance of the helical antenna and the high input impedance of the LNA, the power gain of the entire active system, which ...
This antenna is the one you want lots of gain + great f/b. Three elements for 40 & 30m.Covers on up to 6m. Weighs about 100lbs. Comes with late style SDA 100 controller. There is some control cable. All is dissembled except for the boom. Price is $1550 IF YOU come and pick it...
