I enjoy working with low profile, so I'm using the Kenwood TS-990S running mostly 100 Watt into the home brew magnetic loop antenna for 7 MHz band and one for 20 m.
The size of the 40 m. loop is 2.5m diameter (aluminium tube 50 mm. diam.) placed 4m. above ground level. Fortunately, I have a clear view from South to West.
