70 MHz 4 metre Delta Loop
lthough I would only have FM on 70mHz I thought that making another horizontally polarised Delta Loop made sense for a number of reasons, first it was simpler to mount

40 Meter Parasitic Delta Loop Array
On 40 meters, my experience is that you need at least 20 dB of F/B ratio in order to be able to turn down European broadcasters enough to be able to hear the west coast stations, especially the west coast stations with dipoles and 100 watts
Delta Loop per 50 Mhz
we will use the formula: L = 306.6 / F Mhz = 306.6 / 50.150 = 6.11 m. in practice we will have that each of the three sides will measure 2.04 m
Delta loop various configurations
The wave emitted by the vertical loopmay be polarized vertical or horizontaldepending on the feedpoint location vertical polarization is preferred when the antenna is low

50MHz to 28MHz RX Converter The concept of the rx converter is quite simple and nothing really new. the local oscillator is a standard colpitts crystal oscillator producing the 22mhz lo signal
