FROM Mr.
SUBJECT: Inspection Report No. 2 - AN-67 Loop Antenna with
1. Project Description:
This project is to develop a collapsible HF loop antenna, designated
25X1A5a1 the AN-67, developed by This includes the
development of everything bu the capacitor. Specifically, the end
product must show that the entire antenna, with the final capacitor, can
be collapsed into 31 cubic inches and not more than four feet in diameter
when it is erected and in use. The antenna is tunable over the frequency
range of 4 - 30 MHz and has an input inpedance of approximately 50 ohms
resistive over the same frequency range. The AN-67 will handle RF power
up to 60 watts.
2. Contractual Information:
a. Initial Cost: $Ii-8,215
b. Request for Procurement Action: 12 January 1966
c. Initiation Date: 7 February 1966
d. Completion Date: 7 August 1966

6. Contractor's Performance:
a. On schedule and expected to remain so: No (See Project Status)
b. Within obligated funds and expected to remain so: Yes
c. Satisfactory technical progress: Yes
7. Project Status:
In reviewing the project with Mr the 25X1A5a1
p ~ project seems to be
going smoothly. The project is not as far along as it was first planned,
but there is nothing to indicate that the final delivery will be affected.
build an experimental model of an inflatible torus laminated with
aluminum foil and polyurethane impregnated dacron fabric. - 25X1A5a1
has made several inflatible satellite antennas. Mockups
of this torus have been made and tested with satisfactory results.
The design of the tuning mechanism is complete and a breadboard
was constructed. Although this mechanism is rather compact it is not
going to be the ultimate solution because a final model will use a
much smaller tuning capacitor. It is not within the scope of this
contract to have a miniature tuning capacitor or mechanism fabricated.
