21. Topband: Extending the Beverage (score: 1)
Author: k4kyv@hotmail.com (Donald Chester)
Date: Thu, 11 Jul 2002 03:11:41 +0000
At present my Beverage is 390' long, 10' high and terminated at the N-Northeast end. It does a pretty fair job at rejecting noise from certain local sources and comfortably pulling in signals that ma

I wish to thank all who have responded regarding length of the Beverage. Most recommend limiting the extended length to about 580' as the best compromise between lobe width and f/b ratio. I could eas

(Re the ground wire laid directly under the Beverage) Vic, W1WCR says that the classic Beverage is designed for groundwave or extremely low angle skywave at LF and VLF, and is dependent on the wavef

Before the power limit rule was changed to output power, the legal limit was 1 kw DC input to the final. For CW, that translated to a maximum of about 750 watts output. With the change in the power l

Thanks to all who responded to my question. The consensus of replies is that on 160 and the hf bands, plenty of CW ops run the full legal limit, and more than a few run considerably more. High power

Author: k4kyv@hotmail.com (Donald Chester)
Date: Thu, 27 Jun 2002 05:42:54 +0000
Ten feet of vertical drop I think you are absolutely right. However, sloping the wire saves having to put up an additional support pole at the end of the antenna plus guy wire. The antenna itself se

The QST article recommends using non-metallic support poles for flags and pennants. The 16 ft. high vertical section six feet off the ground calls for a 20 ft. mast. I'd be interested to know what s
