FEATURES
The 917A-ISP Wireless internet antenna, is designed for deep fringe systems were standard panels or
smaller yagi's just don't cut it. The antenna enables "Polarity Flexibility" in any given application. Low cost
configured with dependability allows use even in strong signal areas for greater margin, which means less
service calls. The new 5/16" element design decreases the effects of rain and light snow
deterioration often seen in similar antennas.
The heart of the 917A-ISP, the folded dipole, provides a virtual flat match for over 30 MHz. The gain has
been designed to roll-off quickly above range limits to prevent receiver overload from high power services
above 930 MHz. The heavy duty two piece boom and 5/16" elements, give the ISP service confidence for
superior performance and longevity.
The 917A-ISP is a DC grounded antenna designed to work with many radios including the Wave Rider.
The 3003 and 3004 Wave Rider radios have internal DC circuit protection built in. The 3000 model will
work with the 917-ISP, but will default to the outside antenna once it sees a short.
