Subject: CS-8 Broadband Antenna (Modified),
Frequency Range 30-1000 mc.,
Submission of Information Concerning
Quotation for
Reference: (a) Quotation letter dated 22 December 1958
Pursuant to a review of Reference (a), the bidder has discovered certain
information necessary for review of the referenced quotation was inadvertently
ed. Therefore the bidder submits the toliowing inrormation;
1.. The gain for the subject antenna will be 5 db over dipole for the
frequency range of 30-60 me and 6 db over dipole for the frequency
range of 60-1000 mc. The above statement should be considered as
a part of the specifications for the subject equipment.
2. A brief description of the development program contemplated by the
referenced quotation is as follows:
The development program will consist of a mechanical stress analysis
of the antenna - structure, the preparation of new drawings and bill
of materials, complete electrical tests on the antenna and the
preparation of a report and an instruction book. Special problems
whichwill have to be solved are the design of a new tapered line
balun, the determination of a suitable location for the supporting
mast, the design of apparatus to hold the antenna so that it may be
easily rotated for polarization chan'ge_and, most important, the
design of a special section for the front end of the antenna in
the 30:1 bandwidth. For structural reasons, this
front end should be rugged so as to hold the halves of the antenna
together, but for electrical reasons, the metal parts, of this front
end should.be small so'as to preserve the desire4 pattern character-
istics . It"iS felt that the front end de sign,ts,;certainly feasible,
but it will Ice, ,a considerable amount. of investigation: As with
any new antenna design, ,it will take a consi4e.le'unt o? time
to complete all the detailed designs-and dratdings.
