EI3IO Antennas

The picture above shows the current antenna configuration on the 20 metre tilt-over tower at EI3IO.

Currently the lower antenna at EI3IO is a 3 element Cushcraft A3S triband yagi at 20 metres agl. Above the A3S is an 18/24 MHz rotary dipole. The top antenna at 25 metres is a 6 element 70 MHz antenna fabricated from a Create 50 MHz yagi. Below the 6 element 70 MHz yagi is a 7 element 50 MHz 6M7JHV from M2.

Hanging from a cross arm at the top of the tower are a quarter wave inverted L for 1.8 MHz, which is also used as a 3/4 wave inverted L on 5 MHz as well as a 7 MHz Delta Loop. Also suspended from the tower is a half-sloper for 3.5 MHz, which is additionally used on 10 MHz.

Also available is a 30 metre centre fed inverted V doublet, the centre suspended at a height of 22 metres above ground in a convenient tree. This antenna is fed with 600 ohm ladder line and is mainly used on the 3.5, 5, 7 and 10 MHz bands.
