3 March 1956 on H-2061 :antenna System
1. A theoretical calculation is to be made by Ito determine the
operational range of the antenna-crystal detector system as now
formulated. This is of interest for Band 3 especially. This
c~.lculation may possibly be checked with information received by
2, A possibility of improving the crystal-video signal to noise ratio
by finding an optimum crystal position in a waveguide was discussed,
This is a,plicable to Bands 7 and 3. Further information on a
reference for this work is necessary. It was thought that any degree
of optimizing the position of the cr:istal would result in a frequency
sensitive device.
3~ The final design for the Bands 1 and 2 dipoles with reflecting screen
is not complete, size compromise in reflecting screen size with top
and end flaps is necessary to obtain useable results for both bands,
I. The assembly of the Bands 3, 4 and 5 helical antennas mounted on a
carbon-filled, fiberglas plate was tested as a unit, come unwanted
reflections from the fiberglas itself was observed. The thickness of
the fiberglas surface is to be decreased,
5. The horns for Bands 6, 7 and 3 are on order. The Band 3 horn with
flange, which was tested at NRL will be tested along with the horns
on order. These horns are without flanges.
6? The mechanical configuration of the antenna unit was discussed, The
color of the radomae is to be "3630 which is a lustreless light gray.
T-?e overall. mechanical design of the structure was inspected. This
design is in agreement with the operational use ::f the equipment,

7, An increase in antenna spares t,3 include one each of the inc'ividual
antennas was desired by the customer. Lata for each antenna should
include;

contract negotiations will be necessary to cover any additional
