I purchased a bunch of custom cables from this ebay supplier: wifi_expert
http://www.ebay.com/itm/USA-CA-LMR400-PL259-UHF-MALE-to-DIN-7-16-MALE-Coaxial-RF-Pigtail-Cable-/371303924873?var=&hash=item5673704489:m:m2D85KEUXnQzoxMF8dchqGw
The cable is marked "Times Microwave LMR400" and the workmanship looks
very good. They were assembled in the USA, got them in less than a
week. I have a bunch of Suhner F-F DIN adapters ($$$ but got them very
cheap) so was ok with a male DIN to mate to the LDF5 male DIN and the
other end PL259. I have 12 of DIN-PL259 in custom lengths in service
inside for over a year, no problems QRO 10 to 80m.
I suspect they will make whatever you want, if the connectors are
available. There are lots of other cables and connectors on ebay from
wifi_expert.
One thing I did was to make an Excel spreadsheet loss calculations of
every cable run amp output to antenna feedpoint, with every cable type,
length and its loss at band it is for. The goal was under 1db total and
all cable runs calculated at less than 0.9db 10 to 80m. LDF4 on 80 & 40
and LDF5 20 > 10.

I have never used 7/16 DIN connectors. It seems impossible to find an
adapter to go from 7/16 DIN to UHF. As hams, we need to plug into our rigs
and antennas with UHF connectors - How do you jump the gap??

Why? Are all your systems at UHF?
No. In my business we use nothing but 7-16 DIN nowadays and it does not take
long working with them (like 5 minutes) to realize how superior they are,
even if just mechanically (at HF). And of course I have a good supply on
hand, being in the biz.
So when I ran all new hardline out to the towers a few years ago, it was an
easy decision to switch to DINs on the main lines and on jumpers - at each
end of the hardlines - to the point where I encounter a device with a UHF
connector that is inconvenient to replace, like a wattmeter, balun, etc.
