This makes the end-fed antenna perfect as a multi-band antenna. Totally fantastic is the fact that the antenna is resonant at half a wavelength or a multiple of this wavelength. This makes the antenna convenient for (DX) long distance connections. You are on air within 5 minutes! An additional advantage is that the antenna can easily be polarized vertically. Put a telescopic mast against a pole, hook the antenna to the top and slide it out.

BenefitsĪn advantage of end-fed antennas is of course the simplicity, especially for fieldwork this is a huge advantage.
