For Sale:
E. F. Johnson Model 250-849 "Antenna Meter"
Even though it says "Antenna Meter" on it, it is really just
a normal HF SWR bridge. It is in a black box about 5 inches
long, 3 inches high, and 2 inches deep, with an SO-239
connector out each side. The actual meter movement is an
edgewise meter movement. It is interesting to note that the
front panel is marked "Waseca, Minn. U.S.A" with no zip code
given, so that should give some indication of its vintage.
This unit is in very nice condition. I can not find a scratch
on it, and the paint is very good, except for some very slight
wear on the heads of the screws on the bottom of it, due to
the fact that there are no feet on the bottom. $30
Other HF SWR Bridges and wattmeter available:
SWR Bridge
This is the standard HF SWR bridge in a gray crinkle box
about 6 inches long and a couple inches square, with SO-239
connectors coming out of each end. It works fine. $12
ParaDynamics PDC-1
This HF wattmeter / SWR bridge will read forward and
reflected power with either 100 W or 10 W full scale. It
is relatively small, making it great for mobile operation.
Of course with a 10 W scale, it would be useful for QRP
operation as well. $18
Prices do not include shipping from Florida.
Thanks.
