Magnetic loop antennas (MLA) have an extremely com-pact design and are therefore a good alternative to long-wire antennas. The AN-48x is supplied with adapters to connect the antenna to BNC and RCA sockets. Connected the added windings on both antennas together with twisted wire pair. I would like to stay with 50ohm feedline and avoid remote preamp if possible, also if anyone knows of a schematic for a longwave antenna tunner anywhere on the web then that would be great. £47. 0 The AN-48x runs on two AAA batteries (not included). Hello, You can easily get this antenna to 150 khz by putting a fixed disk capacitor in parallel across the tuning cap. It is optimized for 50- 503 mHz. As a caveat, we also performed a model by feeding the loop at the mid-point of the horizontal base wire. Band selection, remote tuning, including optional loop rotation, is controlled by a microcontroller driving a high-resolution stepper motor. Ø The base amplifier + antenna should be placed on a window sill for best performance. Ø The antenna comes with two unique antennas that plug into the base amplifier. The old tuning cap is out of a old valve radio, not sure of the pf but I would be guessing maybe upto 400-500pf max. de: Electronics & Photo. 105.

Excellent performance was possible and many improved loops were designed over the years. Even on less than optimum bands [20, 15 and 12m] the performance should be more than adequate. Noise levels were very high during this contest, so this Loop really helped me. The loop and the capacitor together form an electrical parallel resonant circuit. Resources listed under Loop Antenna category belongs to Antennas main collection, and get reviewed and rated by amateur radio operators. Experiment with proximity and position of the Loop Antenna and the radio for best reception. The antenna comes with three types of connector cable and a ferrite coupler for connecting to different types of radios, like the Tecsun S-2000, Tecsun S-8800 and Tecsun PL series. The ferrite loop is not working as an antenna and when I turned it, I didn't get any difference in signal strength. The loop has recently had a significant design change to improve LW/MW and SW reception. The antenna is constructed by adding vertical quarter wavelength shorting pins to a horizontal four-leaf-clover-shaped loop patch. Their radiation resistance, however, can be improved by adding more turns. The small loop antenna characteristics are very similar to those of the small dipole antenna. Sold by radiwow UK and sent from Simply place your AM radio in front of the loop antenna, tune to your AM radio station and adjust the signal tuner knob on the Loop Antenna. The only way to reduce the interference is to use a reject filter at the input for the TX frequency. £49. The SuperLoop: A super-sized terminated corner-fed broadband loop.
