The 40/30 Pyramid antenna
I have something here that I believe is new. If it isn't then that's ok ,I don't use EZNEC or read antenna articles much. I like to innovate. This antenna is an innovation. I have read about a sloping two band Delta loop but it used two feed lines mine uses one. It is called the 40/30 pyramid

Build a Multi-Band Mono Delta Loop
Make up a 14 MHz. delta loop using two separate lengths of 10 meter plus 10 centimeters each of No. 12 or No. 14 stranded copper wire and connect them in series with an insulator as shown at the bottom of Fig 1. The 10 cm extra wire is passed through the end hole of the insulator then looped back to the wire element to form a splice for later soldering
Antenna Delta loop bidirettiva
Questa e' una antenna adatta per HF realizzabile senza troppe difficolta', l'unico inconveniente e' che necessita possedere di un discreto spazio dove installarla e di almeno quattro supporti a cui agganciare i loop

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
