JRE BBA-1 overview
Changing antennas for every band adds setup time and another variable to the bench. I use the straight BBA-1 when consistent coverage across a very wide sweep matters more than maximum signal coupling. The right-angle BBA-1R is the better route when cable bend clearance drives the mount.
- Frequency coverage from 1 MHz to over 6,000 MHz without antenna changeouts
- Return loss of −35 dB @ 450 MHz, −25 dB @ 930 MHz, and −20 dB @ 2 GHz
- Approximately −20 to −30 dB performance relative to a matched quarter-wave antenna
- 50 ohms characteristic impedance for a stable test-equipment connection
- 1 watt power rating for both transmit and receive setups
- SMA Female connector with long shaft and mounting nuts for straight-through mounting
- Compact 1 x 5" (25 x 125 mm) body for enclosure installation
The deliberate efficiency trade makes sense when the DUT or test frequency changes often and the system can budget the added path loss. At $150.00, the BBA-1 buys broad coverage and fewer fixture changes. Its straight SMA Female connection suits an antenna that should project directly from the mounting surface.
