Dual Ferrite Isolator circulator for VHF. I\'ve got two of these in the 140 MHz range, price listed is for one unit.
This unit came to me used, along with some cavities that I needed for another project. I have no idea of the history or status of this, so it is sold as is, and you would probably need to retune it yourself. Looks to be in fine shape, but does have some very minimal rusting/corrosion. Isolator comes with a 60 watt load.Sinclair’s ‘I2’ series isolators and circulators offer superior performance in a compact
rugged package. Careful temperature compensation and top quality components
ensure high isolation with very low insertion loss over their full operating temperature
range, and offer a high degree of RF and magnetic stability.
Circulators are supplied without loads. Isolators come equipped with a variety of load
terminations.
Threaded holes in the steel casing allow surface mounting to any non-magnetic
material. Aluminum brackets can also be supplied to isolate the unit from the
mounting surface to increase stability.Insertion loss (typ) Tx to Ant. = 0.7 dB
Insertion loss (max) Tx to Ant. = 1.0 dBMax VSWR = 1.25:1
Max Power input - 125 watts
Typical isolation = 75 dB
