SMA Dipole 2.4, 5-6 GHz Antenna — JRE ANT-245

For over-the-air WiFi and Bluetooth work, I use this compact dipole to put the two commonly used bands on one fixture. The swivel-and-tilt coupling makes antenna position easy to set, then repeat from test to test.

• Dual-band coverage at 2.4 and 5-6 GHz for WiFi, Bluetooth, and other wireless devices
• Return loss better than -15 dB from 2.2 to 2.7 GHz and 5 to 5.8 GHz
• VSWR less than 1.5:1 across the WiFi bands for a consistent equipment match
• Approximately 2 dBi gain with 50 ohms characteristic impedance
• 1 watt power rating for transmit as well as receive work
• SMA Male connector on a 4.25" (110 mm) antenna body
• Swivel-and-tilt elbow for fixing orientation around the DUT and cabling

Inside an enclosure it operates in the near field, so treat it as a coupling device rather than expecting a free-space pattern. Keep its position and the DUT placement fixed when repeatability matters. At $23.00, the ANT-245 is the focused, economical choice when the test stays in its stated bands.
