Ferrite rod loading


On both 630m WSPR and 160m FT8 RX I have had great success using the FT817ND and the coax to my 2m big-wheel antenna. Just a mains earth was used in my case. If you cannot use this I expect a simple external ground would do instead.  The tapped ferrite rod is shown. This was used as an ATU. The coax is quite short and the big-wheel about 5m at its highest. At its lowest the coax is about 50cm off the ground. 

On 160m my noise level is S8-9. Despite this I can copy loads on FT8.
