Likwise on 500 Khz compared to my 1/4 wave inv L is was well down. Small loops, micro Probes and Ferrite rod antennas work after a fashion but are no substitute for the real thing ie Verticals, Rhombics, Vee beams and Large loops Yankee style. de Mal/G3KEV ----- Original Message ----- From: "Andy Talbot" To: Cc: Sent: Friday, December 16, 2011 11:21 AM Subject: LF: Wellbrook Loop I've just read the review of the welbrook Loop in the latest RadCom, and wondering if anyone here knows the preamp configuration.
