[ARC5] A particular version of the URC-4 beacon from the early 1950s

Colleagues,

I hope that this group is the proper one to address an inquiry related 
to a particular version of the URC-4 beacon from the early 1950s.

I accidentally came across an old Polish newsreel from 1953, which can 
be found at:

 From 6:10 it elaborates the case of two US agents of Polish descent, 
Dionizy Sosnowski and Stefan Skrzyszowski, who were parachuted into 
northern Poland in early November 1952 along with three RS-6 and an 
URC-4. These agents were actually lured into a trap organized by Polish 
security under Operation Cezary, and subsequently arrested. They were 
eventually condemned to death in the following year and executed.

More details of their equipment from their trial can be found in another 
1953 newsreel, which can be viewed here:

My questions are related to the particular version of the URC-4, which 
can be seen on the said newsreel. The set bears telescopic counterpoises 
and a tripod, which I assume were not typical for the ordinary URC-4 
survival radio. Yet it's still powered from a typical JAN BA-1264 
battery. The beacon was to be used as a navigation aid for future 
clandestine airdrops in Poland, which did not commence given the fate of 
the agents.

My questions are:

(1) Was that particular version of the beacon with the telescopic 
counterpoises made in any significant quantities?

(2) Could the 'agent' version cover frequencies other than 121.5/243 MHz?

More imagery on the case can be found here:

Another photo of the URC-4 allegedly airdropped with Sosnowski and 
Skrzyszowski in 1952, albeit with counterpoises detached:

Any suggestions related to the said URC-4 version with telescopic 
counterpoises are welcome.
