The 900 ISP Stack Kit is a 2-Way Combiner for stacking two of the 915ISP or 917ISP antennas. When stacked at 22” for the 915ISP and 27” for the 917ISP apart in a vertical polarization, the stacking kit will increase the forward gain by 3.0 dB. Note– the beam width is about 1/2 the width of a single 915ISP or 917ISP. When using the kit, pointing accuracy becomes very important for best usage.
This kit also can be used for vertical stacking when Horizontal Polarization is desired. When Vertically stacked the Azimuth beam width is the same as one 915ISP or 917ISP. It is very important to use the same polarization at each antenna point.
