The Yaesu FT-200 / Henry Radio Tempo One ises an 11-pin Amphenol '86' / '78' series connector for its external HV DC power supply.
The pin assignments, for this connector, can be found on page 15.
http://www.radiomanual.info/schemi/FT200_FT250_user.pdf

Amphenol/WPI Series 86 is the plug that fits the Series 78 sockets.

11-pin Plug: 86-CP11
11-pin Socket: 78-S11
Strain Relief hood for cable: 86-3-24
Cover with no strain relief: 86-3-13

You can purchase these from any Amphenol/WPI retailer/distributor -- such as Allied Electronics, Newark Element14, that have remaining stocks !!!
Some eBay resellers sell these connectors and cable sets for Collins or Heathkit HV power supply to transceiver.

IF you use Tarn-X, you want to follow with distilled water to remove the acid.
Some paste silver or chrome polishes work well.

You get few chances to clean it well, once it is back in operation.

comments on the Henry 2K series (Nov. 1997, contesting.com)
http://lists.contesting.com/_amps/1997-11/msg00248.html

This Henry looks like it was stored in a barn or garage.

1. DE-ENERGIZE for Safety. 
While unlikely to have a garage on the oil capacitors,
still perform steps as if it was plugged in earlier.

2. CLEAN IT.  I actually clean the silver plated coils as well.
While I am cleaning -- good eyes will find cracked wire insulation,
Tarnish/corrosion on switch contacts and mechanical controls.

3. DETAIL IT, and check critical components (DVM/VOM, visual inspection)

4. REPLACE missing or failed parts. 
Henry Radio and RF Parts in California will have almost anything you would need.

5.  Do you have the Glass RF tubes and Glass Chimneys?

It matters, for quality audio.

Professional audio technicians deal with Impedance (Z) matching as well as
Balanced and UN-Balanced Inputs / Outputs on a regular basis.
In RF, you deal with Antennas.
At antenna feed-point you use BAL-UN or UN-UN and Z transformation (1:1, 4:1, 9:1).
Coaxial cable is an UN-Balanced transmission line, BUT a Dipole Antenna is a Balanced radiator.

Whether you are working with RF or Audio -- they BOTH follow AC Theory and are both Electromagnetic Waves.
These principles have not change since discovered in 19th century.

Balanced to Unbalanced Wiring

All Things Kenwood
Amateur radio transceivers and transmitters use UN-Balanced audio inputs.
The Kenwood Hybrids (TS-520S) desire a High-Z (impedance) input.

John -

Good observation, even the Redi-Match (gamma match) feed point.  
Their TCM U440-11 retails for $123 CDN, the MFJ/Cushcraft A449-11 retails for $120 USD.

Yes, this T.G.M. Communication UHF beam (11-element) looks like
the old 1970s Cushcraft A430-11S design
http://www.cushcraftamateur.com/pdffiles/951426.pdf

and the current Cushcraft A449-11 design (1990s)
http://www.cushcraftamateur.com/pdffiles/a449-11.pdf

The specifications are nearly identical.
I would inquire with TCM what they are using for Element to Boom clamps.

TCM was founded in 1993 and acquired the old Mini-Products (Erie, PA) HQ-series of Mini-Beams for HF.
TCM renamed this antenna line, the MQ-series then updated and enhanced the old HQ-series designs.

R -

I have looked closely at the top section photographs.
 It appears that the R-9 design has adopted design elements (capacity hats) from
earlier Cushcraft and Hy-Gain designs ... for this antenna to cover the 80 meter CW and Phone segments.

This new R-9 antenna DOES have substantial mass at its top --- so guying us a REQUIREMENT.
I would not consider installing unless you can accommodate the guying.

You should not have any problems.  The antenna pattern is influenced not only by the geometry you described, but also the height above the ground (incidental reflections).

As Phil said, put it up and measure actual results.  
The other option is virtual computer modeling ....

Dallas / Maxim DS1020 Data Sheet
http://datasheets.maximintegrated.com/en/ds/DS1020.pdf

The DS1020 is an 8-bit programmable delay line that reproduces an input logic state at the output after a user-programmed delay. Delays can be varied over 256 steps with resolutions of 0.15ns, 0.25ns, 0.50ns, 1.0ns, or 2.0ns (see table). Total delays range from an inherent 10ns minimum delay to a maximum 520ns. The DS1020 is programmed over the 3-wire serial port or the 8-pin parallel port. The DS1020 is TTL- and CMOS-compatible, and capable of driving up to ten 74LS-type loads. Both leading- and trailing-edge accuracy are specified.

The DS1020 is an effective, economical solution to the designer working with the complex timing requirements of mismatched ASICs or other components, or with the strict timing tolerances of increasing system clock rates. With the DS1020's programmable outputs, the user can precisely adjust timing to application needs and improve system performance. Innovative circuit designs and factory laser or EPROM trimming enhance accuracy without the need for external components, saving cost and space.

This was the intention (Earth to Mars communications) of the AMSAT-DL Phase 5 :
 P5A Mission, first proposed in 2002.
http://www.ticket-to-mars.org/

An essential technical element of the Mars P5A mission is the ground station for supervising and controlling the Mars bound probe. The 20 meter parabolic antenna at the Bochum observatory (IUZ) was refurbished and reactivated.
The facility, now operated by AMSAT-DL has already proven its capability through the reception of NASA and ESA probes like Mars Express, the Saturn probe Cassini and the comet probe Rosetta.
In the spring of 2006 a team from AMSAT-DL even received signals from the American space probe Voyager 1 at a total distance of approximately 14.7 billion kilometers.

The P5A Mission proposal was turned down for ESA funding last year.

Allen --

650°F to 750°F will handle 99% of you hobbyist soldering needs.
For apprentices and novices (at soldering), variable temperature is BAD NEWS.

Soldering relies on a number of variables that needs to be properly balanced.

1. Solder Alloy formation (Sb/Tin-PB/Lead; RoHS/No-Lead).  
http://en.wikipedia.org/wiki/Solder
Tin/lead solders, also called soft solders, are commercially available with tin concentrations
between 5% and 70% by weight.
The greater the tin concentration, the greater the solder’s tensile and shear strengths.

Alloys commonly used for electrical soldering are 60/40 Tin/lead (Sn/Pb)
which melts at 370°F or 188°C and 63/37 Sn/Pb used principally in electrical/electronic work.

The 63/37 is a eutectic alloy, which:
* has the lowest melting point (183°C or 361.4°F) of all the tin/lead alloys; and
* the melting point is truly a point — not a range.

2. Soldering Techniques and Tip Selection
http://en.wikipedia.org/wiki/Soldering

Soldering is a subset of the larger techniques that include Brazing and Welding.

SOLDER IRON TIP SELECTION:
Match the characteristics to the joint to the tip that will perform the work,
The Temperature is a SET ONCE step determined by below and Solder Alloy formulation.

1. PROFILE (Chisel, Screwdriver, Conical, Single Flat, Gull-Wing)
2. SIZE of TIP PROFILE (1/32" to over 1/4"), Hakko uses Metric measures, so convert as needed.
3. OVERALL MASS -  Match the size and profile of iron tip to work.

===
OVERALL RECOOMENDATION for Thru-Hole and Point to Point wiring.

Screwdriver or Chisel Tip ; 1/16" or 3/32" size; Set station to 700 °F ;
Use a 60/40 or 63/37 solder with mild flux (Kester 44) of 0.031" to 0.020" diameter.
The 0.025" diameter for your solder is a good compromise,
if you are doing connector and fine PC board work.

ELECRAFT has soldering recommendations, on their web site, or Kit Builders.

The LaCrosse model that LOOKS exactly like your WT8005 is the newer WT8115U model.
It sells for only $5.00 more, and features an Outdoor Temp. sensor.

The Heathkit EK-2B is the 1950s - 1960s educational kit for Basic Radio course.
As I remember, this is an All-American Five style design ---
Tube filaments and pilot lamp are wired in series with the AC Line Voltage (no isolation transformer).

When this kit was designed (1950s), USA line voltage of 110 to 115 Volts was common,
today 120 to 125 Volts is more common.
For example, my residential line voltage, this evening, is 125 Volts !

The #755 is a well-known replacement (longer life) for the #47 lamp.
Very inexpensive at $1.35 for 2 lamps.

You mention that this High-Band VHF (Land Mobile allocation) antenna is 20 feet (6.1 m) in height.
This is likely a Collinear antenna of 9 dB gain, at this height.

To use for 2-meters, you would have to fabricate NEW coax pieces,
 since this antenna is TOO SHORT (Wavelengths matter) at 1.79 meters .

DIY Fabrication -- you can reuse the antenna base mount and composite radome to DIY build
an equivalent 2-meter model.

Clocked designed and made in China.  

Likely a simple processor (PIC, Atmel, Arudino, etc.) with 4 switch settings "programmed" in firmware.
Need someone willing to HACK the design (just like Asian mfg. do for USA designs).
