If you want to use an FY6900 DDS signal generator or other contemporaryRF signal source for radio alignment, you cannot employ the old "connect a loop of wire to the output" trick. It will not work. The 6900 and many other newer signal generators often see wire loops as short circuits. That will cause the output to shut down, and potentially damage your signal generator.
This compact coupler contains a loop antenna and the necessary capacitive isolation to be compatible with the FY6900 and similar devices. The plasticenclosure keeps those components safe. It measures about 2"Longx 1-1/4"Widex 5/8"Deep. (55mm x 35mm x 15mm). Depth at the connector extendstoabout one-inch (25mm).
The BNC connector makes it compatible with many contemporarygenerators. The included Male > Male adapter makes it easy to connect the coupler directly to your generator, as shown in the first photo. Alternately, you can use your own BNC to BNC cable of any reasonable length. If you have already purchased an FY6900, it comes with the perfect BNC cable.
NOTE:If you don't own an FY6900 DDS Signal Generator yet, check out the complete packages that I sell. The bundles include a generator, this coupler, a non-metallicalignment tool assortment, plus 24 pages of detailed, full color instructions showing you how-to use these items to align transistor radios and getting them to track properly. Look for them in the Test Equipment section of my Childhoodradio store. Purchasing the bundle, rather than the coupler, alignment tools and FY6900 will save you some money as well.
I also sell specialty cables that convert from the BNC coupler connection to vintage Amphenol-styleconnectors used by RF generators such as those from Heathkit, B&K, Eico and others.
Save your gear, save some time, and preserve your sanity. Grab one of these couplers or, better yet, the complete bundle for your bench today.
Prompt, careful shipping from the US as always.
