Unless otherwise published I will join overhead at 1500 calling intentions on the Unicom channel then descend dead side as per standard procedure.
Going to assume circuit height will be 1000 QFE.
7of9, why not 2,000 feet for your OHJ?

Radiotelephony Reports at Unattended Aerodromes
Introduction
4.150 Where an aeronautical communications frequency is allocated for
use at a United Kingdom aerodrome, all RTF communications are to
be conducted on the allocated frequency. For licensed aerodromes,
allocated frequencies are promulgated in the UK AIP. A common
frequency (135.475 MHz) known as ‘SAFETYCOM’ is made available for
use at aerodromes where no other frequency is allocated (UK AIP GEN
3.4 refers) to enable pilots to broadcast their intentions to other aircraft
that may be operating on, or in the vicinity of, the aerodrome.
4.151 At some UK aerodromes, air traffic movements may occur outside
the promulgated hours of watch of Air Traffic Services (ATS). In order
to improve the safety of these aerodrome operations, pilots should
broadcast information on their intentions to other aircraft that may be
operating on, or in the vicinity, of the aerodrome.
4.152 The phraseology to be used at an unattended aerodrome, as described
in this section, is not to be used at aerodromes with ATS in attendance.
Where ATS is provided, the relevant ATS unit will issue appropriate
instructions.
4.153 All transmissions at unattended aerodromes shall be addressed to
‘(Aerodrome name) Traffic’. No reply to an unattended aerodrome report
shall be transmitted.
4.154 Pilot reports are described for a Standard Overhead Join. This procedure will allow pilots to determine the runway in use and to orientate
themselves with the circuit direction and other traffic. As specific joining and circuit procedures exist for some aerodromes, pilots should refer to
the UK AIP to establish the procedure to be followed.
4.155 Unattended aerodrome reports are made at the discretion of the pilot.
However, to ensure the traffic awareness of other pilots is correctly
maintained, if a pilot elects to make reports, all those reports not listed
as ‘optional’ should be included. Optional calls may be included if
additional traffic information is likely to assist traffic organisation or to
enhance safety.
4.156 Monitoring of unattended aerodrome reports is not a substitute for
visual observation and pilots must maintain traffic awareness and
lookout even when making such calls, as not all aircraft may be
monitoring radio broadcasts.
4.157 Transmission of unattended aerodrome reports does not confer any
right-of-way.
4.158 Pilots shall comply at all times with the Rules of the Air Regulations, in
particular the rules for avoiding aerial collisions.
Additional Procedures for the Use of SAFETYCOM
4.159 SAFETYCOM is not an Air Traffic Service and no aeronautical ground
station is associated with SAFETYCOM.
4.160 SAFETYCOM is a single common frequency and pilots should be aware
of the possibility of congestion and breakthrough. It is particularly
important when using SAFETYCOM that RTF transmissions identify the
aerodrome name (suffixed ‘traffic’) in order to indicate the relevance of
the report to other aircraft. Transmissions must be correct and concise.
4.161 SAFETYCOM transmissions shall only be made when aircraft are not
more than 2000 ft above aerodrome level, or not more than 1000 ft
above promulgated circuit height (if applicable) and within 10 NM of the
aerodrome of intended landing.
4.162 Where an aerodrome lies within controlled airspace, pilots are to call
the appropriate ATSU and ensure that they obtain clearance to enter the
airspace.
