The Tarheel 40A-HP arrived yesterday and is installed.
Based on impedance measurements performed without the base matching coil the Tarheel 40 meter radiation efficiency is 5 to 6 dB better than the ATAS-120. Add to that the new 200 watt transceiver and my 40 meter signal is improved by 8 to 9 dB.
You'll notice that, especially on RX.
