The device is stated to have toroid cores on each side of the line conductor
so as to provide a DC short to the antenna side of the box. On the
transmit side, it may be AC coupled, which is fine when the right size cap
is used for RF. The cores with their windings act as RF chokes while
allowing a DC bleed off for any antenna charge.
There was a similar device, (maybe the same reviewed in QST (?CQ) with a
photo of the inside and it had pretty much the same circuit. Think that was
last year or the year before.
