It is designed for through-hole mounting in metal surfaces. Its compact design offers minimal wind resistance and comes with a 12 inch pigtail lead with a female N connector. The photographs below illustrate the sequence of assembly for the MOB245HM thru hole mount. The mount requires a 3/4" (1.9 cm) hole in a flat metal area with a thickness of 0.020" (.05 cm) to 0.040" (0.1 cm). 1) Feed the lead-in cable from the top until the bushing assembly is in position to drop into the hole. The bushing should be tilted at a slight angle and fed into the hole. The threaded top of the bushing will not fall through the hole. 2) Thread the lock nut onto the busing. Be sure the "O" ring is in the groove of the lock nut before tightening. 3) The lock nut should be tightened until it comes in contact with the surface and the "O" ring is fully compressed. 4) Attach your desired length of cable to the 12" (30.5 cm) lead-in cable pigtail female N connector with a male N connector. 5) Keeping in mind, this cable should be held as short as possible and shall be a low loss, 50 ohm coaxial cable. www.RFM.com E-mail: info@rfm.com (c)2008 by RF Monolithics, Inc.
