Hi to all.

 

I am thinking now about the design of a short vertical antenna, for MF mobile use in next winter season.

 

To night I’ll test this first configuration : a 2 meters high tube (2 cm of diameter) and a top hat (wheel shape) 80 cm of diameter. It needs about 2.4 mH base coil tuning. The TX is 3 Watts output. Base voltage is 2,2 kV RMS.

 

I’ll test this small antenna to night, beginning at 2000 TU on WSPR2 MF band. The expected ERP is about 1 mW.

 

All reports be welcome. Note that to night the testing antenna has his base on the garden with a ground earth rod, so it is not installing on my car.
