The 28MHz halo up at the top of the 5-6m vertical section (which was the coax feed to the 28MHz halo) was removed and replaced by a spiral inductance/ top capacity hat consisting of around around 8 "spiralling in" turns in the space occupied by the original halo. Seeing my initial reports from M0BMU I am some *5-6dB stronger* than I was before, I guess because more of the antenna current is in the vertical section. The measured antenna current is not much different though. *Please listen for me on 500kHz WSPR* and let me know if I am now stronger than before. 73s Roger G3XBM -- ------------------------------------------------------------- http://g3xbm-qrp.blogspot.com/ http://www.g3xbm.co.uk G3XBM GQRP 1678 ISWL G11088 --0015175d036258cfb50477b6933c Content-Type: text/html; charset=ISO-8859-1 Content-Transfer-Encoding: quoted-printable Today I modified my 500kHz antenna.
