SUBJECT: Inspection Report No. 1 - AN/B-62 with
25X1A5a1
1. Project Description:
The AN/B-62 is a loop antenna assembly which is designed for use
with the RR-49 receiver to permit its use in DF applications. It
consists of a shielded ferrite core antenna, antenna tuning network,
and frequency band switch. The tuning capacitor provides a means of
resonating the loop antenna over each of the frequency bands; the
frequency band switch is used to select the proper loop inductance
for each band. Energy is coupled from the loop antenna to the RR-49
receiver by a low impedance tap on the loop winding. A coaxial cable
assembly is used to connect the AN/B-62 to the RR-49. A "pocket
carrying card" is provided and is used to mbunt the AN/B-62 when it
is used under the operator's clothing. A "handle" in the card is
provided for handheld operation.

-7. Project Status:
25X1A5a1
Except for the tuning capacitors, all electrical parts required in
the AN/B-62 assembly have been received at- Delivery of the 25X1A5a1
capacitor is estimated for 21 April. All metal work (cases, brackets,
etc.) is complete. The coaxial cables (to connect the antenna to the
receiver) have been assembled with a BNC connector on one end. The
machine shop was completing fabrication of plastic vernier discs and
the dial locking mechanism (essentially a lever arm which applies a
pressure to the serrated edge of the vernier disc when the lever arm
is placed in the lock position).
A crude version of a more positive seating connector plug (coaxial
cable to receiver) was exhibited. It appeared to "seat" in a satisfac-
tory manner. The molds for this connector are available and the initial
sample molded plugs were to be available within the next several days.
The connector plugs will be molded of a hard rubber material.
25X1A5a1
An initial one-half dozen ferrite rods are being wound for elec-
trical test purposes to establish acceptable winding tolerances. Also,
as advised to check the input impedance of the new production
run RR-4+9 to insure compatibility with the antenna. (The prototype
antenna was designed by~using a service test model RR-49) 25X1A5a1
Hopefully, no problem should result.
An initial quantity of ten AN/B-62's were requested for delivery.
during the first week of May. This, of course, is dependent upon
receipt of the tuning capacitor.
