They've expanded it a bit!

Speaking of 1.25m, check out what just showed up yesterday. :O
I've never seen TNC connectors in person before. :P

Halo antennas are funky:
Although some writers consider the gap in the halo antenna's loop to distinguish it from a small loop antenna – since there is no DC connection between the two ends – that distinction is lost at RF: The close-bent high-voltage ends are connected capacitively, with a RF electrical connection completed through displacement current. Despite the abrupt reversal in voltage across the gap, the RF current bridging the gap is continuous (although possibly momentarily zero).
The gap in the halo is electrically equivalent to the tuning capacitor on a small loop, although its stray capacitance is not nearly as large as needed for a tuned loop: Capacitance is not needed since the halo antenna is already resonant, but since some small capacitive coupling is present anyway, the arms of the dipole are trimmed back from 97% of a quarter-wave each to restore resonance. Moreover, the halo ends are often pressed even closer together, to increase their mutual capacitance and the ends then cut even shorter to compensate, in order to make the radiation pattern even more nearly omnidirectional, and to produce even less wasteful vertical radiation (for a horizontally mounted halo).
"Norman Road Closure"
A washout on the Stillaguamish River closed it.

in reply to Neil E. Hodges • •I wanted this because my FT-991A does 2m and 70cm, but not 1.25m.
The same merchant also has models for outputting 2m, 70cm, 33cm, and 23cm. 👀

in reply to Neil E. Hodges • • •Very nice!!
I have the older version of the L222-28HP by Down East Microwave. I use it it with an old transverter interface that I modified so that the transverter automatically gets switched in when I change the band on the IC-7300 to 10m.
Q5 makes some really nice gear!

in reply to Neil E. Hodges • • •that's not a TNC; that's an N connector.
TNC (threaded nut connector) is about the same dimensions as
BNC (bayonet nut connector). N connectors are the same thread size as UHF (universal high frequency), but the interior are the same as BNC/TNC.
So, it is possible to remove the nut from a BNC and plug it into an N.
