After feeding every kind of data into the computer and analysing the results, Kazusa-Kameyama in Kimitsu City was selected for this week.
The plan: start at Kazusa-Kameyama, pass through Sakahata to Yokoo, cross Mount Daifuku, continue through Tozura, and reach Yoro Valley.
Outbound
Sunday, September 21.
Tamachi 4:52 → Tokyo 7:21 → Kisarazu 6:42 / 7:25 → Kazusa-Kameyama 8:33. [Translator's note: the inconsistent Tokyo time is reproduced from the original.]
Tamachi.
Tokyo Station.
Unusually on underground platform 2, and unusually already at the platform.
Arrived at Kisarazu.
‘I came using Suica and want to go to Kazusa-Kameyama.’
Supplement: Tamachi's paper-ticket machine could not sell a ticket because it was outside its range.
Kisarazu.
Arrived at Kazusa-Kameyama.
So, about that planned extension to Kazusa-Nakano…
According to the GSI map, the route passes through four tunnels.
The first. I should have brought a headlamp.
Second.
Third.
Fourth.
Reaching the suspected location
9:48．
Hmm? …As a wise predecessor said, ‘Suspect a brand-new electricity service pole.’
Looking for clues.
Recently erected? …All the more suspicious.
Corrugated conduit runs inward. A clear trodden path beside the pole.
Zooming farther along… then approaching.
Whose is it?
That logo, and the familiar sound of the fans…
This rack…
JOSADA TELECOM!
Its Mount Oyama station in Kanagawa Prefecture:
The rack manufacturer is DDB Unlimited:

There does not appear to be a communications connection.
Probably operating standalone and recording to storage media.
Overview
It is probably better to see the whole arrangement before the photographs.
Configuration
It looked like the following diagram.
Two Beverage wires.
They are strung with a 5 m longitudinal offset.
Lengths estimated by pacing and similar methods.
Element height above ground: 2 m.
The gap between the two wires is narrow, less than 1 m.
The rack-to-antenna connection looks temporary.
The A side in the diagram is left disconnected.
Equipment
End-fired phased beverages.
Is it this?

Location
Nuda, Kimitsu City:
It will probably never be visible in satellite imagery.
Perhaps the rack might be, at most.
The direction looked a little north of north-northeast, around 21°.
That said, its directivity should not be particularly critical.
The following diagram is an estimate; SRI if wrong:
The three chimneys of Anegasaki Thermal Power Station are visible in the centre background.
Old roads, forestry roads, trodden paths—and a defensive ditch? left in the photo below—crisscross this area.
Exploring those looks fun too.
Note: there is a ‘Beware of land leeches’ sign on the climb.
Observations…
The photographs do not enlarge when clicked.
Feed end
Near the rack.
A, the upper wire's feedpoint.
Unused.
B, the lower wire's feedpoint.
This one is connected.
It feels like a temporary, one-sided arrangement running on one lung.
Termination end
There is also a 5 m offset at this end.
A, upper wire termination.
B, lower wire termination.
Other construction details
One mast along the way.
Perhaps about 60 cm between the elements?
Trees are used too.
Suspended like this.
Triumphant return
Objective achieved, so instead of Yoro Valley I will double back to Kazusa-Kameyama.
Farewell.
Started down at 12:55.
Back at Kazusa-Kameyama Station, 13:41.
Obtaining a boarding-station certificate.
Kazusa-Kameyama 14:27 → Kisarazu 15:36 / 15:47 → Shimbashi 17:16 / 17:20 → Tamachi.
Departing Kazusa-Kameyama.
Kisarazu.
Let the 15:37 for Chiba go and take the Kurihama train ten minutes later.
Shimbashi.
Arrived at Tamachi.
To the fare-adjustment machine. Apparently it uses character recognition.
A fare-adjustment ticket comes out; use it at the automatic gate.
Comparison with other companies
A comparison of receive-only sites related to HF digital fixed stations; click to enlarge, 670 KB.
In other words, the figure excludes sites used for both transmission and reception, and transmit-only sites.
These do not appear in the Radio Station Information Search, so one must search with one's eyes.
[Added September 23, 11:00] The full overview is ready too; click to enlarge, 630 KB. I arranged it in callsign order.
