Topbanders, Here is my two cents worth: If one uses a 1/4 wl inverted-L, then it can be easly matched by an UnUn. Examples can be found at: http://www.amidoncorp.com/aai_cost_ununs.htm The UnUn label

Dear Topbanders, N4CC and the Battle Creek Special group are working to get an amplifier for Nelson, 4S7NE, so he will have a better signal on 160 meters. In Dayton, the collection barrel will be at

Dear Topbanders: We have acquired a suitable amplifier for 4S7NE and it works well. Now we need to get it to Nelson in Sri Lanka. Does anyone have a secure way to get it there in the next few months

My first comment is the 400 foot tower is over 3/4 wavelengths tall, electrically, so any shunt feed system would send most of the RF energy skyward, like off the end of a longwire. For the guyed tow
