OHR PARTS & COMPONENTS

Parts and Components
Years ago Oak Hills Reseach supplied parts and components to the QRP building community. We're reviving the tradition, starting with a few hard-to-find parts that we have access to in quantity. We can't always give you the lowest price on the market, but the difference will be relatively painless if you include your parts with another order from OHR or Morse Express.
Please note that we do have a minimum $10 order exclusive of shipping, but that minimum can be met with any combination of products from OHR, Milestone Technologies, and Morse Express. A good starting point would be our Tools Page.

These are all factory fresh parts (we use NO surplus parts in OHR kits, and you shouldn't either!), some of them made exclusively for Oak Hills.

PL-259QA Push-On Adapter
A quick-disconnect for your coax cables! We've used these on the OHR test bench for years, and finally found them in commercial quantities. Just screw your existing PL259 onto the adapter and push the adapter on to your SO-239 coax jack, providing a solid friction fit that is fine for temporary installations or where you need to change cables often. .

OP-PL259QA PL-259QA Push-on Adapter $5.00

PL-259Q Push-On Plug
Standard PL25 9 plug with the push-on sleeve. Direct fit for RG8 or use RG58 with the standard adapter (not supplied). Sleeve can be removed for use with exisisting PL259s, just back the shell off onto the cable and screw on the new push-on sleeve.
