Broadband Surge Arrestor for DC-3000 MHz applications
Help protect your equipment from the effects of lightning induced surges with the broadband SA90-SMA
Surge Arrestor. This DC-passing surge arrestor operates with frequencies up to 3 GHz and helps with
protection from lightning strikes. The arrestor is compatible with the IEEE 802.11b standard.
FEATURES
• Easy installation for Masterclock GPS antenna systems- compact
design fits in cramped installations
• Weather resistant in mated condition
• Quality protection at a competitive price
• Good return loss characteristics
• Low throughput energy during lightning strikes
• Contains 1 each surge arrestor with SMA female and SMA male connectors and a18” – 45 cm low loss
coaxial pigtail (SMA female to SMA male) - everything needed to install the surge arrestor either
outside adjacent to the antenna or inside at the receiving hardware.*
• For maximum protection 2 units can be installed - see rear of sheet for details.
