Ciro Mazzoni Automatic Magnetic Loop Antennas

Ciro Mazzoni Automatic Magnetic Loop Antennas are ideal stealth HOA and small-space loop antennas. They provide exciting new capabilities to limited space operations with unparalleled reliability and dramatically higher power handling compared to other transmitting loops. These are considered to be the best small transmitting loops available in the world! They are constructed with tough, attractive, aircraft grade aluminum. In spite of their compact size, these antennas automatically adjust to resonance throughout a wide band range: the MIDI Loop tunes 80 through 20 meters, the BABY tunes 40 through 10 meters... without any coverage gap! Now, THE STEALTH LOOP adds even more versatility for the Amateur who is shackled by antenna restrictions. Use it on the ground or on a table! Click on the STEALTH below for More Details! For each LOOP Antenna, MIDI, BABY and THE STEALTH LOOP, frequency information is directly transferred from your radio (ICOM, Elecraft, Kenwood, and Yaesu) to the included ATU 2.0 Controller, by RS-232 or Interface Cable. The Loop Antenna tunes automatically to the radio frequency or manual tuning is available with the ATU 2.0 USB Keypad, also included. If you need a very-high quality antenna that is concealable and operates at respectable power over a wide frequency range, then Ciro Mazzoni Automatic Magnetic Loop Antennas are a great choice!

Ciro Mazzoni Portable Power UP CONVERTER 12 to 24VDC for Loop ATU

Ciro Mazzoni UP CONVERTER 12 to 24VDC Power Converters are specially designed to facilitate portable operations of the STEALTH Loop Antenna and ATU 2.0 Unit. While it is common to use a 12VDC battery or vehicle power during portable ops, it is uncommon to have 24VDC on hand to power the STEALTH Loop and ATU. UP CONVERTER solves this dilemma, and it is guaranteed to be RF quiet, unlike some poorly designed DC to DC converters. It features two digital volt meters to monitor the Input and Output voltages. The UP CONVERTER is the perfect accessory for battery operations of the ATU 2.0 supplied with the MIDI Loop, the BABY Loop and STEALTH Loop, during power outages or off-grid, and it can be used for other 12 to 24 VDC projects. Two different 12VDC input connector cables are provided, and a 2.5mm DC connector cable for the ATU 2.0 plugs directly into the 24VDC output connector.
