MFJ-1786 Magnetic loop Covers 10M,12M,15M,17M,20M,30M A low noise unit  but may  be a bit high cost for an entry operator. Does not require any height and is ideal for the operator with no backyard I can cover most of the world using this antenna . It does require tuning as the time of day changes or more so the air temp. But overall this is my most used antenna

Good cost for the bands covered and will handle upto 1.5kW An itneresting antenna one that could be used in any back yard or on top of a flat roof.

Working the Inoisphere

An excellemt starting unit for an entry operator with not much backyard An excellent antenna if you are short on room - lean it up against a post on a 6 foot pole, lat it at 45 degrees in the roof space and you can qso with Russia. the secret is the Cap hat and the top loading.  The only problems is the birds trying to sit on the wires of the Cap Hat
