During the past few years 'TT' has reported and discussed the controversial views first put forward by Professor Mike Underbill, G3LHZ, and M J Blewett, G4VRN, of the University of Surrey at the 1997 IEE Conference on HF Radio Systems and Techniques (IEE Conference Book No 411) in their paper 'Magnetic Loop or Small Folded Dipole'. This argued that the recognised good performance of small 'magnetic loop' antennas could be explained provided that the dominant mode of radia- " tion was accepted to be that of a small folded dipole. This paperwas noted in 'TT' in November 1997 and resulted in comments by Dr John Belrose, VE2CV; Alan Boswell,G3NOQ;John Crabtree,KC0GGH; Tony Henk, G4XVF, and several other readers ('TT'February and July, 1998, February and May 1999).
