Just the job  Time owned: 0 to 3 months
The quality of the PCB is excellent as is Mike's service. Used part list as per G4AON. Small problem was that the M3 6mm screws specified are not long enough for the task.

Measured performance using a DG8SAQ VNA is very good. Spent a little time adjusting the matching coil to give an excellent match, insertion loss and isolation.

The relay coils have one side connected to the ground plane so if driven from a computer (e.g.) PIC etc then the driver needs to source a voltage rather that sink a current. This is not an issue if a mechanical switch is used.

Simple build and works well  Time owned: 0 to 3 months
Mike offers a high quality print board and parts list to make your own antenna switch, which takes an hour or so to assemble and test. There is a drilling template on the web site, so even the "hard" job of drilling the case is as simple as it can be, short of offering a ready made case!

I used a Hammond 1590 series case and readily available parts. The cost is roughly half that of a ready made unit, which may not even work as well as this one.

Payment is via Paypal and shipping to the UK was very fast.
