890-940 MHz Waveguide Antenna Waveguide (can): Is round. Is 9 and 1/3 inchs in diameter. Is 16 and 1/2 inchs long. Probe: Is parallel to the bottom of the can. Is vertical with respect to earth. Is 5 and 29/32" from the back of the can. Is 3 and 11/32" long including the brass part of the N-Type connector. Notes: When using wire mesh at these frequencies use mesh that is a minimum of 1 inch mesh. I strongly recommend 1/2 or 1/4 inch mesh. This antenna requires careful measurements and cutting. -m-
