Multi-band loft-mounted dipoles for 40, 20, 17, 15, and 10m
Amateurs are always after the Holy Grail - an antenna that will work on all bands, is inconspicuous, effective, but above all inexpensive. Unfortunately, you seldom find something that fits all these factors.
This antenna has nothing new about its design, but it does bring together quite a few useful ideas and characteristics.
• Fully no-tune antenna system for five popular HF bands
• Suitable for SWLS, QRP, M3 licensees and PSK31 operating plus occasional useup to 100W, but watch out for RFI at high powers. DO NOT USE A LINEAR!
• Uses non-inductive (zig-zag) loading for 40m
• Feed point balun reduces RF pick-up and interference making it quiet.
