If you want an easy-to-build 40 meter antenna suitable for both home and field use, you can't beat the folded dipole.   Kevin Loughin (KB9RLW) tackles this project with his usual down-to-earth enthusiasm and creativity. You won't need expensive materials or excessive time to design, build, test, and use this antenna. Here are a few comments from Kevin: In all the years I've been playing radio, I've never built a folded dipole. Boy have I been missing out! These are amazing performers.

Thanks to Jim Haslett for making this useful and often necessary antenna accessory.  Choke baluns help keep common mode currents off your coaxial feedline and, thereby, protect your transceiver and boost efficiency of your antenna system. ----- Thanks for joining us today.

If you want a fun and educational antenna experience, please try this 2 meter Halo Antenna Kit from Moonraker.eu. Matt from "Tech Minds" takes us step-by-step through the assembly and testing process for this omnidirectional, horizontally polarized VHF antenna. Here are some comment from Matt: You can purchase this antenna from Moonraker.eu via the following link: https://www.moonraker.eu/hlp-2-144mhz...

Thanks to Kevin Loughin (KB9RLW) for this interesting antenna comparison.   In my experience, the folded dipole antenna tends to be a bit more broad banded than the "classic" HF dipole antenna. The folded dipole requires a 300-ohm balanced feeder and an antenna "tuner" for optimum performance. The folded dipole antenna is useful if you don't have a coaxial cable feed line.  The folded dipole is compact, easy to set up, and suitable for both home and field use. Here are some general comments from Kevin: I did some comparisons between a regular old wire dipole and a folded dipole made out of window line. Both cut for 20 meters and both installed similarly.

Thanks to Gil of the "RadioPrepper.com" youtube channel for this useful and often necessary accessory for random wire multi-band end-fed wire antennas. The step-by-step assembly process is clear and easy to understand.  This would make an excellent weekend project. Here are some general comments from Gil: Building a 9:1 UNUN for a random-wire multi-band end-fed antenna using an FT-140-43 toroid instead of the usual T106-2. Presumably the ferrite toroid works better for the lower bands, 40 and 80m, and as well for the upper bands, I would guess up to 10m, not sure about 6m. It remains to be tested in an upcoming video. I should have measured SWR with a 470-Ohm resistor between ground and antenna wire but I forgot. A random wire by the way is any wire which is not a half-wave...
