The 711-ISPA Commercial Wireless internet antenna, has been designed to give you optimum performance for the smallest package size. The new 5/16” element design decreases the effects of rain and light snow deterioration often seen in similar antennas. The heart of the 711-ISPA, 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 740 MHz. The heavy duty boom and 5/16” elements, give the ISP service confidence for superior performance and longevity. The 711-ISPA is a DC grounded antenna designed to work with many radios.
