People, do as I say, not as I do. The Icom 710 as depicted above is installed in the TV
cabinet of the Island Packet 350 and was so installed since the author did not use the cabinet
except for storage.  Therefore, after carefully measuring the cabinet and getting the specs on
the M710, a decision was made to purchase almost resulting in a grand foul up.
Consideration was not given to the protruding wires and leads behind the unit so therefore,
the unit had to be "stomped in" meaning the unit was pushed back with the wires and leads
firmly against the liner to the rear of the cabinet. A mounting bracket/shelf was constructed
of 7" x 1" teak with the  uprights anchored to the bottom of the cabinet with cabinet grade
90 degree brackets and brass screws. The top shelf is secured to these brackets by wooden
dowels so the top shelf can be removed by pushing up underneath, after removal of  the
For the IP 350 owner, due to the curvature of the hull, down and in, as well as the door
latching mechanism on the inside,  the unit cannot be installed a fraction of an inch higher, a
fraction of an inch down or to the side, however, the unit can be mounted in the center of
the shelf by inletting the liner behind for the wire and lead clearance.  In this manner the unit
was installed without cutting the liner behind, the inside of the door and cabinet edge had to
be milled a bit for mounting of the microphone cord as depicted in the photo.The next
planned installation will be a Pactor modem for e-mail installed to the side of the unit,  either
on top of the shelf or below.  Mounted underneath the observer will note the Prowatt 400
inverter used to power the laptop for downloading weather faxes.
Inasmuch as "Don" of HF Radio is an apostle of the through the hull ground plate group,
Gordon West is not, two through the hull ground plates were purchased and installed, one in
the starboard cockpit locker as far forward as possible, and the other in the port cockpit
locker as far forward as possible. Copper foil was installed and attached to the plates and led
to the antenna tuner installed behind the water heater and on the inside of the starboard
bulkhead. The starboard backstay had been removed by the author and taken to the rigging
shop and two insulators were installed by the rigger, the topmost about three feet down from
the top, the bottom about eye level. GO-15 antenna lead was attached to the  aft end of the
antenna tuner and then led up through the cap rail with a standard through the hull
attachment to the starboard backstay, connected at about six inches above the bottom
This installation is satisfactory, but just!  From the beginning the author was on the air and
checked in with all of the nets in range, no difficulty was experienced in transmitting or
receiving. Underway and under sail, one ground plate is exposed but since each plate
provides the minimal square footage plus the copper foil for transmitting, there is no
reduction in performance.  Of course this is no problem with the boat anchored, in a slip or
underway under power.
Now, if the author had the opportunity to do the installation again from the beginning, it
would be done differently to say the least. The unit in question was purchased just before a
pending cruise and there was a long waiting list for the new model 802 with the remote
speaker and panel so in order to get SSB capability for the cruise the M710 was purchased,
otherwise the M802 would have been purchased.  In regards to the IP 350, the body would
mount easily on the shelf behind the settee cushion and under the present installation, the
speaker and panel would mount on the shelf on top of the electrical panel to port of the radar
monitor as depicted in the photo above.  Further, rather than purchasing and mounting the  
through the hull ground plates, the author would follow Gordon West's advice and install
enough copper foil connected to through hulls for proper grounding.  If this did not work,
the through hull plates could be purchased.
