Wim PE1WVD komt verslag doen over de bouw van zijn efficiënte magnetische loop antenne voor HF.
De loopantenne heeft een diameter van 2 meter en kan gebruikt worden op de 80, 40, 20, 17 en 15 meter.
Voor meer info kan je contact opnemen met secretaris Jan PA0SIM (a31@veron.nl).
Receiving Antennas are Different
by Eric KL7AJ
Almost every ham radio station can benefit from a separate receiving antenna (or several!) While reciprocity applies to both receiving and transmitting antennas, the priorities are different. Effective receiving antennas are optimized for best signal to noise ratio, not necessarily the greatest gain. There are countless interesting means of building high signal to noise ratio receiving antennas and we will explore some of these in ‘Receiving Antennas are Different’.

Tonight @ 8 webinars are live-streamed, allowing you to watch the presentations and ask questions online.
They can also be viewed on a later date on the RSGB website and YouTube.
