For several RSLs I have used a wire antenna, (an <br>> inverted L) to great effect. The Earth mat consisting of wire netting <br>> laid on the ground. Height is might as always, but even with only 20 <br>> metres, we were getting into Europe! I have reception reports to prove <br>> it. I have also used a single 1 1/4" tube steel mast, with a 'top hat' <br>> to increase top capacitance. I believe Radica used to do AM antennae <br>> using a lamp post. (you can get a lamp post for about £300) The <br>> standard RSL AM licence is for 1 watt. This gives a similar coverage to <br>> FM at 25watts. Oh yes, and I designed and built my own transmitters, <br>> using valves!<br>> <br>> Within the specified 5km radius for community radio, AM will do the job <br>> nicely. (very important to get some good audio processing though) Also, <br>> with fewer stations now on AM it could get better!<br>> <br>> Anybody want to know more? mail me at phildawson@lemonmail.co.uk.<br>> <br>> Phil Dawson<br>> FANTASY RADIO97FM<br>> Devizes<br>> Wiltshire.<br>> <br>> <br>> <br>> On 15/09/2015 12:00, cma-l-request@mailman.commedia.org.uk wrote:<br>> > Send cma-l mailing list submissions to<br>> > cma-l@mailman.commedia.org.uk<br>> ><br>> > To subscribe or unsubscribe via the World Wide Web, visit<br>> > http://mailman.commedia.org.uk/mailman/listinfo/cma-l<br>> > or, via email, send a message with subject or body 'help' to<br>> > cma-l-request@mailman.commedia.org.uk<br>> ><br>> > You can reach the person managing the list at<br>> > cma-l-owner@mailman.commedia.org.uk<br>> ><br>> > When replying, please edit your Subject line so it is more specific<br>> > than "Re: Contents of cma-l digest..."<br>> ><br>> ><br>> > Today's Topics:<br>> ><br>> > 1.
