Highlights
- Coverage from about 40 kHz to 30 MHz (VLF through HF).
- Compact, stealthy element: three-section aluminum whip, approx. 2.6 m (8.5 ft).
- DXE-AVA-3 Active Matching Unit (included): high-impedance buffer between short element and 75 Ω coax.
- Excellent strong-signal handling: +39 dBm TOI (third-order intercept).
- Flat gain response across band: ±0.4 dB.
- Selectable internal gain via jumper: −6 dB / 0 dB / +6 dB to suit noise environment and element size.
- Low visual impact; stainless hardware; insulated mounting plate; optimized for quiet RX away from metallic structures.
- Use singly or as part of 2 / 4 / 8-element phased arrays for directivity and noise reduction.

- HF receive antenna for contesting and everyday operation
- Phased receive arrays for directivity and noise rejection
- Portable and expedition receive systems
Installation Notes
- Mount at ground level on a ground rod in a clear area away from metal, towers, buildings, power lines, and other antennas.
- Provide a good RF ground/counterpoise per manual guidance.
- Route coax cleanly; use quality 75 Ω cable; weatherproof all outdoor connections.
- Adjust the AVA-3 internal gain jumper (−6/0/+6 dB) to match local noise conditions and element length.
Package & Compatibility
- Sold individually as DXE-RSEAV-1; also available bundled with bias tee (DXE-RSEAV-1FVI), and in 2/4/8 element sets.
- Works with DX Engineering phasing/combining systems for receive arrays.

FAQ
- Can I transmit with the RSEAV-1?
- No. It is a receive-only antenna and cannot be used for transmitting.
- What feedline should I use?
- Quality 75 Ω RG-6U (quad-shield flooded recommended for outdoor/direct-burial runs).
- Can I use multiple elements in a phased array?
- Yes. 2, 4, or 8-element arrays are supported with appropriate phasing/combining units.
