Ground blocks have a low insertion loss, and they usually are not figured into the
attenuation calculations unless five or more are used—in that case, calculate an
extra .2 dB into the trunk attenuation. The ground block has a 75 Ω impedance, a
return loss of >40 dB, and a wide application frequency range. The 60-0545-000
Ground Block consists of two female in-line F connectors and a separate screw hole
binding for attaching a ground wire. The grounding block has two mounting holes,
allowing it to be mounted to a flat surface. Two styles of 60-0545-000 Ground Blocks
(Type A and B) are available and may be used interchangeably. Their mounting
dimensions are different. Type A mounting holes are spaced 2.332" on center. Type
B mounting holes are spaced 1.61" on center.
