I plan to operate my 4S-Tuner with a 40m "Doublet" antenna. The doublet has two 1-wire legs, 22 feet each, with a 28 foot 2-wire feedline, which I assume is "balanced". (See URLs below for details).
I have 2 questions.
I recently re-read the manual, which states the following: "With an external balun it will also match antennas with balanced feedlines." However, there are 2 binding posts that share the same internal circuit connection as the output BNC connector ("ANT").
Q1: Can I just connect the "balanced" 2-wire feedline directly to the posts, picking one as the "antenna" and the other as "ground"?
On a related note, it seems that the 4S-Tuner is geared primarily towards high-impedance antennas, such as EFHW.
Q2: How does it perform with an antenna with an impedance close to the nominal 50 ohms?
Thanks much for your insights!
