Pierre,
First having the Wire Antenna Element set at Six Feet (6') High is both an Encumbrance and a Hazard to the general movement of people around and about your Antenna. =2E Look at your two Trees and get a reasonable idea of "How High" you can get the Wire Antenna Element up in the Air. Twelve to Fifteen Feet (12'-15') should be 'doable' with Twenty to Thirty Feet (20'-30') being idea for a Random Wire Antenna that is about Fifty Feet (50') long that is configured as an Inverted "L" Antenna. =2E Consider re-building and improving your existing Antenna as a "Low Noise" Inverted "L" Shortwave Listener's (SWL) Antenna. =2E The LOW NOISE Antenna is basically a "Random Wire" Antenna Element configured as an Inverted "L" Antenna - Longer Horizontal-Out-Arm bending down to a - Shorter Vertical-Down-Leg all the way to ground level - Using a 9:1 Matching Transformer mounted on a - Ground Rod installed at the base of the Vertical-Down-Leg - Using a Coax Cable Feed-in-Line to the Receiver. This is the basic Shortwave Listener's (SWL) Antenna that uses the "Low Noise Antenna" 'design concepts' that were popularized by John Doty. =2E =2E Here are a few Messages related to the Low Noise Inverted "L" Antenna for Shortwave Listener's (SWLs) : =2E Three "Must" Links to Read -wrt- Low Noise Shortwave Listener (SWL) Antenna http://groups.yahoo.com/group/Shortw...a/message/2016 =2E With a Low Noise Inverted "L" Antenna...
