JRE ANT-211 overview
When a bench spans widely separated wireless bands, I reach for broad coverage before repeated antenna changes. The log-periodic ANT-211 supports that work in a compact, conformal-coated form, with connector hardware for either SMA gender.
- Continuous 2–11 GHz frequency range for broad wireless-band coverage
- −10 to −15 dB return loss from 2 to 11 GHz for a reasonable match
- 50 ohms characteristic impedance for standard RF test setups
- 1 Watt power rating for transmitting and receiving configurations
- SMA female termination with included M-M adapter for male or female connection
- 3.4 x 2.1" (85 x 55 mm) including the M-M SMA adapter
- Small log-periodic element protected by a conformal dielectric coating
The ANT-211 is $78.00 and is the broad-coverage option when one antenna must follow a test across many bands. Within a small enclosure, nearby walls, cables, and the DUT reshape its near field, so published free-space behavior is not the setup target. If the work stays in one narrow band and maximum coupling matters more than range, a tuned antenna is the better direction.

- Understanding antenna performance inside an enclosure Why gain, pattern and polarization don't apply in the near field — and why the BBA-1 is the safe choice.
- How to radiate signals using antennas Path-loss figures, gold-standard benchmarking, and enclosure-to-enclosure linking on the bench.
- The RF absorbing foam inside your test chamber Why the foam is the damper and not the shield — 40 dB per wall bounce, and why a bare box gives you unrepeatable readings.
