DB42 MonstIR Pro Yagi Antenna, 80m-6m Package


Package Includes:

  • DB42 Yagi 80m-6m
  • 80m dipole kit
  • 6m Passive element kit
  • Element truss kit
  • Connector junction box
  • DB25 Cable splice


Priced by the foot: $2.00 / ft.$0.00
This cable must be run from the controller/remote driver board to the antenna directly, is responsible for powering the antenna’s EHUs (Element Housing Units), is double shielded to protect from RFI/EFI, and has a UV rated insulation. We do not recommend using this cable for lengths greater than 400ft (see remote driver board).

The voltage suppressor comes in a fully sealed weather-proof housing and helps protect the controller against ESD events like near-incident lightning or static storms.

The DB42 Monstir Pro is currently the largest of the Dream Beam series of  Yagi antennas.

With 5 elements on 20m-6m and 3 elements on 40/30. For those who aspire to the pinnacle of performance, the DB42 provides coverage from 80m through 6m (with 80m dipole kit). The DB42 has a 49 ft looped driven element.  This patented design allows us to make the end loop elements only 39 feet long, yet the performance is as if all 3 of the loop elements are 49 feet long.  The folded dipole loop technology lets the footprint be 40% less than that of a full size yagi,  losing only 0.4dB in gain performance.

The DB42 has a 80M dipole that works with the SDA100 controller for effortless tuning throughout the entire 80M band.  The dipole runs parallel to the boom and uses the end elements as capacity hats, creating zero interaction with the rest of the antenna.

The 6m passive element option for the DB42 adds 3x fixed elements to the antenna, for a total of 8 elements on 6m.  With no interaction or wind load added to the antenna, this option creates a 6m Yagi with 14.0 dBi of gain and 25 dB of front to rear!
