The 3048 Tuned Dipole Antenna is a compact automatic tuning HF antenna covering 2.5 to 30 MHz at 125 W PEP, with one second tuning and a small installed footprint for space restricted base stations.
Continuous tuned coverage across 2.5 to 30 MHz.
125 W PEP for voice (including Frequency Hopping) and data.
New frequency under one second average, memory tune under 150 ms.
Typically at or below 1.5:1 into a 50 ohm input impedance.
Designed to meet MIL-STD-810G for dust ingress; IP67 immersion to 1 m.
Guy radius 4 m and self supporting span under 10 m on a single mast.
Omni-directional pattern with NVIS and medium distance propagation.

3048 Tuned Dipole Antenna delivers a full HF link from a footprint that fits where space is scarce. The automatic tuning HF antenna covers 2.5 to 30 MHz at 125 W PEP, tuning a new frequency in under one second and supporting ALE and Frequency Hopping with NVIS propagation. Plus, a guy radius of 4 m and a self supporting span under 10 m keep the single mast layout tight. Built in high strength alloy, designed to meet MIL-STD-810G with IP67 immersion to 1 m, the 3048 Tuned Dipole Antenna stands up through severe outdoor conditions.
