The following are some typical RF performance guidelines to consider when choosing to use dual-polarized test probes: • Freq. Bandwidths should not exceed 20% in order to maintain

mode pure ortho-mode junctions. ( Low off-axis cross-pol ) • Very low gain feed horns (10 – 12 dBi ) are not recommend for

circular polarized probes with greater than 12% freq. bandwidth
