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. N

So, I'm looking at setting a EWE antenna up - what happens if I simply make it a full loop? In other words, instead of driving 4' ground rods in at both ends I run a wire between the bottom of the te

Hi topBanders!  I live in an area about 10km away from a BC station that transmits on frequency 981khz and whose power is 200Kw. Whenever I had tried to take measurements with a 160m antenna- with th

Thanks, Tom - looks like running that "bottom wire" would be "worth it" 'cuz I have one 4' ground rod near where I want to install the EWE so that saves the cost of buying another rod...Hi Hi. Apprec

Tom: is there data that nail down the horizontal wire to vertical wire ratio? I see in that write up by wa1on mention of 2.25:1 h to v but...is that some rule that can't be violated or.../ For instan

It seems the thread was gone off the original subject, but .... and it may have been mentioned before .... but with my arrays I used an LP-100 with a low power transmitter as a source. The high signa
