[HCDX] Flattop antenna
Does any of you have any experience with the flattop antenna construction and use? I am interested if any of you has simple manuals over necessary equipment and any idea of the costs. I have approx 40-41 metres room for it. Much used as a transmitting antenna in the USA earlier(WSM/KFI etc.). It is said it is very good as a skywave antenna. I refer you to Les Rayburn's Transmitting antenna for beacon XMGR, 185 kHz LW: http://www.highnoonfilm.com/xmgr/xmgr.htm http://www.highnoonfilm.com/xmgr/updates/foofoo.htm I also refer you to Norsk Radio's proposal for a receiving antenna in # 4/1925: http://www.northernstar.no/flattopsmall1.jpg http://www.northernstar.no/flattopsmall2.jpg http://www.northernstar.no/flattopsmall3.jpg In addition the transmitting antenna for Bergen Kringkastingsstasjon atop the Telegraph Building in Bergen ca. 1925-1937: http://www.northernstar.no/bergenkrk3.gif I also refer you to the essay G5RV Multi-Band Antenna by Louis Varney, from RADIO COMMUNICATIONS, JULY 1984: http://www.qsl.net/aa3px/g5rv.htm Svenn Martinsen ---[Start Commercial]- World Radio TV Handbook 2006 is out.

I refer you to Les Rayburn's Transmitting antenna for beacon XMGR, 185 kHz LW: The antenna is actually a ground mounted vertical, with the top, flat portion, making up for the shortness of the vertical part so you don't have to go up 150 or 180 ft. To make it work well, you'll need a really good ground/radial system. John K9RZZ Milwaukee, WI USA ---[Start Commercial]- World Radio TV Handbook 2006 is out.
