The QSDS 1.5e HRT/PEMS antenna volumes appears to be calculated using the
fixed array modifier of 0.05. A HRT with a short range of 60,000 km has a
fixed antenna diameter of 10 m per TNE FF&S p. 53. The QSDS 1.5e TL-9 Basic
Package has the min length of a hull as being 5 m, which would be my guess
as the length of a 10 m diameter array being folded down for storage.

The TL-9 Basic and Improved packages with a 60,000 km HRT has a fixed
antenna diameter of 10 m. Per the note below the TNE FF&S HRT table: "AD:
Antenna diameter, in meters. If the antenna diameter is greater than the
hull length (unmodified by configuration), the antenna must be a folding
array.

On the Hull Size Table, TNE FF&S Mk I Mod p. 11, a 100 Td hull has a length
(L) of 14 m which means that a 60,000 km HRT with a 10 m fixed antenna can
be mounted on a 100 Td hull.  Of course the amount of surface area as
discussed in the reply dated 5/4/2015 6:26 PM has to be considered when
selecting an array. The actual "gotcha" is that the 100 Td Scout/Courier can
not use a small military sensor package. To fix the "gotcha" I would used
the scouts full 45 m versus the base length of 14 m.

Hopefully I'll be posting the TL-9 sensor packages on 5/6 or 5/7. The
Improved and Small Military packages only have adjusted MCr. The Basic, as
already posted, changed volume and MCr.  My calculations for Medium Military
package have returned different volume, , power, cost, and area values using
both the spreadsheet and manual calculations.
