DB36 Yagi Antenna, 80m-6m Package





The boom double truss kit comes standard with the DB42 and is an available upgrade option for the DB36 when utilizing the antenna in high wind and ice loading conditions. The boom double truss not only counteracts vertical loads, but also counteracts horizontal loading to the boom.

Priced by the foot: $4.35 / 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 DB36 is part of the DB series Yagi antennas that use loop elements for 30 and 40M performance.

The DB36 packs MonstIR performance into an antenna that turns in nearly half the radius, and is almost half the weight.   The DB36 is unique among the DB series antennas in that it has a single feed line, and no relays inside the EHU’s.  The DB36 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 the MonstIR Yagi, losing only 0.4dB in gain performance.

The DB36 has a 80M dipole that works with the SDA 100 or OptimizIR controller for effortless tuning through 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.

*Due to the confusion about the EIA/TIA wind ratings, SteppIR is now using PROJECTED AREA as the measurement for our customers to utilize when sizing an antenna to a tower. Projected area by definition is the total perpendicular surface area measured in square feet/square meters, that is exposed to wind. To calculate wind load you always take the largest projected area whether that is from the perspective perpendicular to the boom or perpendicular to the elements. In the case of SteppIR Yagi’s, the maximum projected area will always be the sum of the surface area’s perpendicular to the Yagi elements. This calculation is a constant number and will not change regardless of EIA specification changes. Be sure to present this information (along with the weight of the antenna, turning radius, element lengths, height of antenna, location exposure category, locations three-second gust wind speed, and locations maximum radial ice loading) to your structural engineer and/or tower manufacturer so that they can specify the correct product for your antenna.
