My Rig is a Yaesu FT 991A
My main antenna is the MFJ 1788X Hi Q Loop some fine tuning and a little experience in the beginning to operate the REMOTE CONTROL TUNER UNIT. When one becomes use to its very fine tuning this loop exceeds all expectations.

My Antenna End fed wire (part Stealth) just 17.68 meters (typical ‘Magic’ length) runs from inside the loft area of my house. Attached is a 1-9 unun from an SG 239 Smart tuner, inside the loft away from weather conditions. The wire runs through the exterior wall (Insulated) and down the garden, the exterior length being just 15 metres & terminating on a high wooden post. Inside the loft is 4 various length countepoise.

The many memory settings on the SG239 matching easy with low SWR. I can switch from One antenna to the other giving me full coverage from 80 to 10.


The Mag. loop is installed high on the gable end and as its over 9 meters It is installed horizontally.


The two modes I enjoy are phone and C.W. Perhaps using my Bencher Key more often than the Mic & now with digital modes there is far more to enjoy Incl. 2mtrs/70cms

The Mag Loop is extremely quiet and no DNR required for the Magnetic loop antenna.

2 mtrs and 70 cms. are built-in the FT991A transceiver and for this I have the X-50  high gain dual band antenna which I have placed in the roof space and will now be used more often.
