Mizuho antenna coupler coil LA-2

Popular antenna coupler among Japanese QRPers is a Pi-C type coupler introduced by President Takada of Mizuho. This coupler has large tuning capability than simple L-C type tuners. Unfortunately Mizuho already discontinue KX-series such as KX-S9 or KX-QRP antenna coupler, they still provide a key component LA-2 coil and Poly-Varicon of 340pF. The LA-2 coils cost 1,575yen and PVC costs 820-yen. Their PVC price is bit higher than junk in market. LA-2 coil has its advantage in its accurate inductance and magnetic saturation. JL1KRA Junichi says that he can send a few LA-2 coils to overseas at actual cost.
