Figure 10 Swivel Flanged Coupling
Unflanged Coupling
To couple the unflanged connector with an unflanged RF line, use an
appropriate coupling kit. Refer to Figure 11 while following the
instructions below.
1. Insert the center bullet and bottom it on the midpoint nibs.
2. Position the outer sleeve, with clamping bands, over the input con-
nector.
3. Set the transmission line snugly against the coupling stops.
4. Position the clamping bands evenly about 3/4” from the ends of the
sleeve.
5. Tighten the clamping bands.
Figure 11 Unflanged Coupling
4-1/16” Coupling
The RF connector on Bird 4-1/16 inch loads is built to the Myat Stan-
dard. To couple a 4-1/16 inch Myat Standard to a Dielectric Standard
transmission line a special bullet (Myat P/N 401-081) must be used.
The inner conductor interface is not compatible between Myat and
Dielectric. The Myat inner conductor inside diameter is 1.631 inches
and the inner conductor setback from the outer conductor flange face
is 1.375 inches. If help is needed purchasing a Myat bullet, contact
Myat or a Bird service representative.
