L-Band RHCP Wideband Omni Test Hat
ATH-L-004-RH is a COTS antenna test hat for CSA-L-005-RH, covering 1510 to 1675 MHz across the L-band mobile-satellite allocations. Coupling is 2.5 to 5.5 dB with a 4 dB typical, RHCP, at 2:1 VSWR. Note that power handling is 40 dBm rather than the 43 dBm carried by other hats in this range, which should be checked against the test plan before a high-power functional run. 230 g at 97 x 97 x 34 mm.

PRODUCT OVERVIEW
The fixture is characterised across two sub-bands, approximately 1513 to 1565 MHz on receive and 1620 to 1675 MHz on transmit, reflecting how the L-band mobile-satellite allocations divide in practice. The 40 dBm handling limit accommodates the antenna's own 20 W CW rating with margin for a bench amplifier, but it is 3 dB below the rest of this test hat range and is worth designing around rather than discovering during a functional run. The RF shielded enclosure protects personnel during transmit testing and prevents test energy escaping the test area. The hat mounts to interface features already present on the antenna, requires no spacecraft bracket, and dismounts without tooling. The envelope is 97 x 97 x 34 mm (3.8 x 3.8 x 1.33 in) at 230 g with an SMA female interface, rated -70 to +100 °C operating and storage. CSA-L-005-RH is the matching antenna. Certain small-volume orders can ship within days rather than the months typically quoted for space-qualified hardware.
