70 mhz vertical

20m delta loop  ^pop - This antenna is fed for vertical polarisation, to give a low angle of radiation for DX and also a nearly omni-directional radiation pattern

50MHz J-Pole Antenna  ^pop - Need a general purpose antenna on the magic band? The J-Pole is an easy-to-build and inexpensive device that provides an omni-directional vertically polarised antenna without the need for a ground plane. In technical terms, it is an end fed vertical 1/2 wave which is fed via a 1/4 wave matching stub.

Moxon rectangles for 6 Meters - Moxon antenna for 50 mhz, The Moxon rectangle is a quite broad-band antenna, but it is not quite broad enough to cover the entire band.

Six Meter Moxon Antenna  ^pop - N2MH description and phots of a moxon antenna for six meters band, includes clear pictures, drawings and assembling instruction to build this antenna for 50 mhz.
