Simple Ham Radio Antennas--Ham Radio 40 meter homebrew ground mount vertical

If you're having trouble viewing this video, please enter this title link into your browser search box: https://www.youtube.com/watch?v=2qEQN_FV0Pk. Nicely done video tutorial from K8YIO on how to design, build, and use a basic quarter wavelength 40 meter vertical antenna.  The radiating element is made from interlocking pipe sections, measuring approximately 33-feet/10.06 meters. Be sure to attach a ground radial or counterpoise system to this antenna.  The ground radial system supplies the "missing half" of the antenna.  The number of radial elements can vary from 4 to 120, depending on how much wire and real estate are available.  In my moist tropical environment on Hawaii Island, I've found a radial system consisting of 12 to 16 quarter wavelength wires adequate to produce a low angle of radiation and to keep SWR fairly low.  For the truly adventurous radio amateur, try an elevated radial system.  You'll get the same or better performance using only ...

MFJ-1625 80-6 meter window/balcony antenna with built in tuner (http://www.eham.net/reviews/detail/6876#142223). Accessed on 27 June 2016, 03:56 hrs, UTC. Author:  http://www.eham.net. Please click title link to read the full set of antenna reviews. Comment: Back in the mid-1980s, I bought an early forerunner of this antenna from MFJ for use in a rental home on Hawaii Island.  The landlord wasn't too keen on outdoor antennas (television antennas were OK), so I decided to get a simple, easily installed and easily removed antenna for my radio operations.  In those days, the antenna was sold as the MFJ-1622 Window/Balcony Antenna and came with a telescoping steel whip, a tapped coil for the 80, 40, 20, 15, and 10 meter bands, some wire for a "counterpoise" system, a C-clamp for attaching the antenna to a window sill, and a length of RG-58 to connect your HF rig to the antenna system.  While the coil matched the bands fairly well, I used the antenna along with ...

The antenna use a UnUn (unbalanced to unbalanced) balun to insure a good match between feed line and antenna.  Kevin says this antenna is perfect for QRP operations.  You may want to build one of these antennas for emergency or portable use.  This would make a great stealth antenna as well--easy up and easy down with only a small visual impact.
