웹1일 전 · There are many antenna variants possible with a 1:1 BalUn. Of course, the antenna should have an impedance of approximately 50 ohms in the fed point. It is easily to create a single band dipole antenna. There are also multi-band variants to be devised. This can be done by connecting multiple dipole antennas to the same feed point (cat’s whisker). 웹Baluns usually come in 4:1, 6:1, and 9:1, but individuals can experiment with the frequencies they’re looking to emit.
