That's an interesting idea Red and worth a try. 73 Tom G3OLB WO0W wrote: Perhaps you can take a portable transmitter and manual tuner to the site. At the point where you wish to place an L network, attach the manual tuner and transmitter and adjust the tuner for a good match. Take the tuner

G'Day Topbanders, The PT0S DXpedition is scheduled to sail for St. Peter and St. Paul Rocks the evening of Nov 05 (maybe early Nov 06 because of weather). We expect to arrive on the rocks the morning of Nov 09. The first to go up will be the 160 m station, which we hope to get on the air

Topband: Antenna analysers in close proximity to BC station

Thinking again about this, we have missed out a stage. After measuring the tuner output impedance, we need to make a temporary L network which, when terminated with 50 ohms, looks like the antenna. Now put the MFJ on this terminated network and measure it's R +/- jX values which will represent
