Folks,
At our next meeting we welcome Prof. Mike Underhill G3LHZ to tell us all about magnetic loop transmitting antennas including the latest research. He will bring a selection of loops.
Venue: Woodford Park, Woodley, 8pm as usual, Thursday 27th April.
Further, Mike will address fundamental questions about antennas in
general.
Mag loops offer interesting possibilities where space is at a premium –
a number of them we are hoping will fit in the tea room at Woodford
Park.
Also, if extreme volts and amps are your bag – this is definitely one
for you. I’m no expert (Rael is, M0RTP) but the tuning caps need to be
specially designed to handle the high voltages (often involving vacuums) and the loops themselves need low resistance.
Tuning of said caps offers challenges for micro controller/computer auto tuning so there’s something for Arduino/Raspberry Pi enthusiasts etc. – indeed Rael has done quite a bit of work here.
Refreshments to be served as usual.
Looking forward to seeing you on Thursday.
Many thanks to Rael, our own mag loop exponent, for helping organise this meeting.
cheers
John
