×1
rtl-sdr cheap radio receiver dongle
( tuner based on R820T chip, any brand )
×1
HF up-converter
any HF up-converter made for 0 to 50 MHz should be ok - I've used this one but is already sold out: http://upconverterup-100.blogspot.it/
×1
antenna wire, insulators, poles, connectors per the radio jove antenna manual (page 22 of pdf)
