The lower adapter for the Yaesu G800 & G1000 also fit nicely on the top
adapter. You can also slip a 1.5-inch (nominal ID) schedule 40 steel or
aluminum pipe inside the adapter - very nice slip fit. Drill the pipe with
3/8" holes to match the saddle of the "U" at the end of the adapter and the
thru-holes on the sides of the adapter, then pin the mast with 3/8" Grade 5
or Grade 8 bolts/flat washers/Nylock nuts. I've used both approaches with
great success - just don't make that extra mast excessively long (2-3 feet
max).

The lower mast adapter for a Tailtwister (P/N 51467-10) will fit the
AB-577 antenna adapter (stock number 5820-00-973-0200) just fine.
Unfortunately, the lower mast adapter for the Ham-IV (etc.) series is just
slightly small.
