COBWEBB-Antenna-20m-17m-15m-12m-10m
E'omnidirezionale e quindi non servono rotori occupa poco spazio e su tetto e'discreta

Construction of his Cobbweb antenna
After the success of my first cobweb antenna I decided to build a rigid version for my home QTH
The CobWebb antenna
20m, 17m, 15m, 12m, 10m operation, at 4 meters from the ground for test
Antenna COBWEBB 20m – 17m – 15m – 12m – 10m

4-Band c.o.l.a antenna 20-17-15-10m
Deploying a centre fed open loop half-wave dipole in a square shape lowers the impedance to around 8-12ohms.Steve Hunt G3TXQ, took a different approach and his design uses a 1:4 step up balun transformer to compensate for the low impedance

40m Compact 4-Square Antenna Compact 4-Square Antenna – EA5AVL The EA5AVL 40M Compact 4-Square Antenna was designed to provide excellent DX communications on the 40m band
The K9AY loop antenna for 160 and 80m bands You don't have the space to put up a 4 beverage antenna's, an ewe or a 4-square and want 'good ears' on 160 and 80m? no problems try a k9ay loop antenna
