The EchoTracer2 is a rugged, wideband E-field (e-probe) receive antenna covering ~10 kHz to 200 MHz, with best performance from 160 m through 2 m. It’s miniwhip-class but with upgraded RF design, FM-notch filtering, integrated surge/ESD protection, and professional-grade mechanics for outdoor reliability.

Included

  • EchoTracer2 (sealed enclosure)
  • RVS (stainless) mounting plate
  • 1 m whip — Stainless (RVS) or Brass
  • Bias-T 13.8 V, F-type to SMA
  • Short SMA-to-BNC jumper

Optional

  • RX 75 Ω Line Isolator with integrated ground peg (mast base)
  • INTSAT-170-ELITE 75 Ω short run (1–10 m) from EchoTracer2 to the first isolator
  • INTSAT-170-ELITE 75 Ω long run (feedline mast-to-shack)
  • F-type connectors — 3× outdoor + 1× indoor (free crimping)
Recommended Coax & Isolator Layout
1) Short jumper (75 Ω, 1–10 m) from EchoTracer2 to Isolator #1 at mast base.
2) Long run of INTSAT-170-ELITE 75 Ω towards the shack.
3) Isolator #2 before coax enters the shack.
Order 3× outdoor + 1× indoor F connectors — we’ll crimp them for you.

Key Features

  • Frequency range: ~10 kHz – 200 MHz; best 160 m – 2 m
  • Noise figure @10 MHz: <1 dB typical
  • Strong-signal handling: IP3 ~+36 dBm, P1dB ~+18 dBm
  • Surge & ESD protection: gas discharge tube, transient suppressor, clamp diodes
  • FM broadcast notch: ~20–25 dB attenuation of 88–110 MHz
  • Output isolation: transformer + broadband common-mode choke
  • TX tolerance: up to 2 kW at ~12 m distance
  • Whip material options: brass (~+0.5 dB on VHF) vs RVS stainless (marine-grade durability)
  • Power: 13.8 V via Bias-T, ~150–180 mA

Placement & Height

Install on a non-metallic mast away from buildings and noise sources. Typical heights:

• 160 m DX: ~8–10 m
• All-band HF compromise: ~4–5 m
• 20–10 m: ~2–3 m
• 6 m: ~8–10 m
• 4 m: ~6–8 m
• 2 m: ~2–3 m

Metal roofs or conductive surfaces nearby can act as effective ground planes, improving coupling.

Mini-FAQ

  • Can I use EchoTracer2 in phased arrays? — Yes, it’s compatible with EchoTriad and other phased E-probe systems.
  • Does the FM notch affect 6 m? — No, the notch is narrow and above 50 MHz.
  • Whip material difference? — Brass gives ~+0.5 dB at VHF; stainless is more durable.
  • Nearby TX antennas? — Tolerant up to ~2 kW at 12 m. Keep practical spacing.
  • How to ground? — Bond coax braid at mast base using ground peg for lower noise.
