10 Meters, 2 Meters, and 440 - Only 20 Inches Tall!!

And works well with a small Ground Plane/Counterpoise Meets the NEED for High Performance in Limited Spaces

By using a small flat metal sheet or mesh which is only about 3’ X 3’ that the antenna is mounted to, good (V)SWR and performance result with the COMPACtenna Model 10M/2M/440.

  • [Note: For standard type technology antennas, this small size ground plane would typically be quite inadequate for the 10-Meter band, potentially resulting not only in poor (V)SWR but also RF on the outside of the coaxial shield coming back down toward the radio. This is undesirable for a number of reasons including unpredictable signal patterns with the outside of the shield of the coax acting as a poor counterpoise radiator, as well as noise, and transceiver/amplifier possible concerns.]

Unique Magnetic Field Resonator (Less Receiver Noise), Electric/Magnetic Field Diversity Science & Technology Design

Superior Science Performance in NLOS (Non-Line-Of-Sight) Obstructed Environments

  • Examples such as due to buildings, hills, in valley location, indoor installation.

This provides for a Unique Low Cost Easy Installation Base Station Antenna in an attic as well as a variety of limited-space locations.

Power Rating: 100 Watts HF, 85 Watts 2M; 50 Watts 440

  • [Duty Cycle at max. power rating: Maximum total transmit time of 1 minute in any 3 minute period. Hotter conditions such as higher ambient temperature, sun exposure, lesser air flow, etc. decrease duty cycle.]

Gain: Unity

  • [Due to its Unique Science, Performance is greater than predicted based on gain alone in NLOS (Non-Line-Of-Sight) environments which is the world we live in .]

(V)SWR: Nominal < 2:1 28.3-28.8 MHz (10-Meter Band); 144-148 MHz (2 Meter Band); 420-450 MHz (70 cm Band)

Each Antenna quality tested.
