You described the German use of Frame Antennas as fiction?

You'll find these on their long range rear link
command half tracks. SdKfz 250 and 251
derivatives. And you'll find them on the SdKfz
222 and 232 derivative armoured cars for rear
link purposes.
Case in point, this 232 8 Rad (Fu)

My understanding is that these antennas were for
rear link communications between the armoured car
or panzer group operating at long range from
their larger parent formation.
There's an excellent article over on Army Radio
Sales in the UK on this subject by Hue Miller

More on the 30WS and 80WS, by Hue Miller KA7LXY
It's very interesting that the German scout and
command vehicle set-ups included low medium wave
equipment in the MWEc receiver and the 30WSa and
80WS. this equipment was carried in addition to
the more generally distributed low-vhf equipment
of the UKW series, ( UKW = Ultra Kurzwelle =
ultrashort wave ) with its shorter range of less
than 5 miles.
The apparent logic was to provide a stronger
ground wave signal which would follow the lay of
the land better, over hill country, for example.
of course in motion this was fairly impractical
to operate with a standard antenna, so when you
see photos of German scout cars you will see what
is called a "frame antenna" around the top deck,
which looks rather like a handrail.
This antenna itself was not practical for the
command Panzer ( AFVs ) so these, in addition to
the usual UKW mast antenna of about 1.5 meters
length also carried another robust and heavy mast
antenna with some capacitive "whiskers" from the
top, called "Sternantenna" = "star antenna. The
30WS covers 1000 - 3000 kc/s so it is well suited
to amateur radio operation, either A1 or A3, on
the 160 meter band, simply by supplying the
correct voltages.
