I read somewhere that someone made one of those blocks out of wood. It would probably also be possible to fabricate one out of a piece of plastic, but there are a lot of angles and countersunk holes drilled into it. This is a piece that is going to get brittle over the decades, particularly in planes sitting outside in the sun, like mine. I believe it's worth it to get a new block, because without a good antenna connection, a VOR receiver will be rendered worthless. I know that from experience. And, I think it's a relatively small price to pay to keep a VOR receiver working, considering the price of new avionics....
FSDO's have more important things to do (at least they should have) than be checking on something like this. In my career, I have been ramp checked and line checked out the "wazoo" and they mostly have been more interested in correct documents and paperwork than anything else. Of course if you are faced with a "fed" that is still wearing a blue leisure suit with a white belt, you may be in trouble. LOL
With a mile of highway, you can go one mile. With a mile of runway, you can go just about anywhere.
Kirk, well done on the VOR antenna repair!!! The quicker is maintaining the braid portion sealed from any humidity and condensation. Once water gets in, you will have a mis match antenna and create additional attenuation on the coax. At some point the life of our 150's, they will need to be replaced.
Until the Feds catch you selling suspect/unapproved parts.
What about the window latches that a member made and sold? Are they authorized?
The set I got are indistinguishable from the originals. and in fact are better. I challenge anyone to "prove" they are not original to the plane. There are no P/N's on the originals, they function the same, and anyone can clearly see that they are "NEW OLD STOCK"

Not to derail this thread too much, but the warning I gave was about making and selling aircraft parts. The FAA frowns upon this practice. Their job of catching people who make unapproved parts is made easier for them by simply looking at eBay or similar marketplace or website. The fines can be hefty. Sometimes jail time if it really affects safety-of-flight. Typically the FAA will then look at the maker's customer list and send a warning to everyone who purchased parts to remove them from their aircraft.
We can debate about whether or not such parts are safe or good, and whether or not to use them. That's for the end-user (and/or their mechanic) to decide. I'm only saying that making parts to be sold on certified aircraft is not as simple as printing them on a 3D printer and selling for big profit.
Thanks Kirk and correct you are. All one has to do is read 14 CFR 21.9 (a). Any one advertizing aircraft parts for sale either knows, are "should" know it is reasonably likely to be installed on a type- certificated product and that person should not produce that article unless it is-
