Connecting RF Power To Load
Connect the coaxial RF transmission line to the unit. For the respective Mod-
els 8655B/56B the connections are as follows.
Model 8655B (3-1/8 inch EIA, 50 ohm, swivel flanged)
Note: Use the 3-1/8" EIA Coupling Kit (p/n 4600-020), which
includes six 3/8-16 x 1-1/2" bolt and nut sets, O-Ring, and insulated
center bullet.
1. Insert the center bullet and push into the seat insulator in the facing.
2. Install the O-Ring into the groove, if required.
3. Connect the coaxial input in a straight line and push carefully on the cen-
ter contact to close.
Note: The swivel flange on the load makes connection independent
of a fixed flange on coaxial input line.
4. Insert the bolt sets around the flange connection and tighten evenly.

Model 8656B (3-1/8 inch unflanged, 50 ohm impedance)
Note: Use the Bird Coupling Kit P/N 5-726, consisting of two
clamping bands, an outer sleeve, and the center coupling bullet.
1. Insert the center bullet, and bottom it on the midpoint nibs.
2. Position the outer sleeve, with clamps, over the input connector.
3. Seat the transmission line snugly against the coupling stops.
4. Position the clamp bands evenly about 3-3/4 inches apart, and tighten.
