απο το πιο πανω link του Νικηφορου:* http://www.valcom.ca/welcome.htmlThe first confirmation of the use of radials comes from FCC (κατι σαν το δικο μας ΕΕΤΤ ισως again who recommends to AM broadcasters to install as much as 113 radials each a quarter-wave long to reduce earth losses. To prove its efficiency Valcom in Canada* suggests to install at ground level such a network constituted of 120 radials 34.2 m long (114 ft). Right, excepted that to work on the 40 m band for example, you need a free space of 10m of radius, of course in all directions... I even don't speak yet to work on the 80 or the 160m band... As noted a commentator, the FCC has probably not included in its formula the price of the estate..., Hi!
