The loop antenna and receiver may be hand held or mast mounted.ĥ30 kHz to 1720 kHz +/-3 dB (normalized loop response) The 24 inch square PVC loop may be broken down into components for storage. The design consists of a balanced peaked lowpass coaxial design providing exceptional sensitivity and directivity.įrequency response is 530 kHz to 1720 kHz (broadband). The AM BC active broadband coaxial wound loop is used in conjunction with an AM broadcast Receiver. M-607 - AM BC Active Loop Antenna Price: $440.00 Supplied with fifty feet of RG-174/U cable. The antenna is easily pipe or mast mounted. Operating between 5 kHz, the high impedance E-field antenna contains a high gain signal amplifier and high pass filter for reduction of lower frequency interference caused by dimmers and power lines. Proven reliable, and used in installations around the world for more that ten years, the M-601 is considered a standard among professionals as an excellent source antenna for distributed communications and home entertainment systems.
The M-601C is commercially rugged and suitable for outdoor installations.

The LF active broadband coaxial wound loop is used in conjunction with an LF receiver input circuit. L-950 - LF Active Loop Antenna Price: $460.00 The L-400B broadband filter design enables you to effectively receive the entire LF spectrum from 40 dB above 600 kHz The versatile and proven reliable L-400B may be used with all 50 to 100 ohm input receivers and converters. The L-400B active antenna is a compact 26 inch fully sealed e-probe designed for receiving within the VLF and LF spectrum. L-400B - LF/VLF Active Antenna Price: $210.00 An internal voltage regulator provides better than +/- 1Hz frequency stability.Īntenna probe tested to 2 atmospheres (-66 ft)ġ20 VAC / 12 VDC power pack with 2.5 mm plug Receiver tuning is between 4.0 MHz and 4.5 MHz. rejection greatly improves reception below 10 kHz and its sharp roll-off filter characteristics eliminate BC intermodulation. The externally mounted LF converter contains a low impedance wide dynamic range balanced mixer, with RF, IF and local oscillator filtering. The L-111 combines the proven L-400B active antenna with a sensitive LF to HF converter.
