Something for someone to do.
I don't know whether I've got the know-how or the time to design a homebrew
VHF yagi for the marine band. So, is anyone out there interested in providing a service to all marine band DXers/eavesdroppers of designing and producing *full constructional notes* on a range of marine antennas, and then putting the designs up on a website. All antennas shall principally be for reception. All antennas should be described as covering 156-162Mhz. As far as the yagis are concerned, they should range from 2 to 6 elements. All yagis shall have 4mm (or 3/16") diameter parasitic elements. All parasitic elements shall be secured to boom by nylon rivets as per G3SEK's notes at: http://www.ifwtech.co.uk/g3sek/diy-yagi/#Construction All booms shall consist of either 20mm or 15mm square tubing. The DE for all yagis shall be 8mm (or 5/16"). The DE for all yagis shall be a regular hertz dipole. There shall be some kind of balun. Please, please! |
