If you're having trouble viewing this video, please insert this title URL into your browser search box: https://www.youtube.com/watch?v=jiaHtmOB57Y. This is post # 1006 in a continuing series of "Simple Ham Radio Antennas." Here's simple, effective end fed field antenna for 80 meters.  In this video, NG9D explains the installation, theory, and operation of this easy-to-make antenna suitable for either portable or emergency situations.  The antenna is designed to cover the  3.5 MHZ ( 80 meter band ), and is primarily a NVIS (near vertical incident skywave) antenna.  The high-angle radiation angle of this antenna makes it perfect for local, state, and regional coverage. NG9D made his antenna out of commonly available parts, including approximately 160-feet/48.78 meters of insulated wire , some banana plugs , and an antenna transmatch (i.e. "tuner"). As with all end fed wire antennas, don't forget to have a radial ground or counterpoise system.

Defeat NIMBYS with p-Cells wireless antenna disguised as a wire. (https://www.wired.com/2017/01/wireless-antenna-disguised-wire/). Accessed on 08 January 2017, 02:30 hrs, UTC .

Comment: Cellular telephone companies, amateur radio operators , and shortwave listeners have been fighting for several decades for the right to erect antennas in deed-restricted properties.  The fight has even entered the halls of Congress, as both the ARRL and the NAB have introduced bills to broaden the scope of antennas permitted on private property. A new device called the "p-Cell" developed by Steve Perlman and his Artemis Network may be a way out of this mess by making cellular antennas nearly invisible to self-appointed property police. Perlman says the p-Cell is only 15 mm wide and can be installed by telco technicians directly as a cable.  No pe

If you're having trouble viewing this video, please insert this URL link into your browser search box: https://www.youtube.com/watch?v=TXKZfZQRxW8. This is post #1003 in a continuing series of "Simple Ham Radio Antennas." Here's another great idea for an inexpensive, portable, and simple 20 meter Vertical Whip Antenna. The antenna consists of a lightweight, portable base, a telescoping whip antenna , and various lengths of wire for an uncomplicated ground radial system.  The wire and PVC pipe can be bought at the nearest hardware store or home improvement outlet.  The collapsible telescoping mast, clamps, connectors, UHF connectors, and 50 ohm coaxial cable can be ordered from MFJ . Radial wires vary from 12-feet/3.65 meters to 8-feet/2.43 meters, depending on the band of choice.  You can lengthen or shorten the telescoping whip to fit whatever band you choose.  In this video, the whip antenna can be adjusted for 20, 17, and 15 meters without excessive S

Ham Radio--How to make a Frame Aerial for the Medium Wave (https://g4ydm.blogspot.com/2017/01/ham-radio-how-to-make-frame-aerial-for.html). Please click link or insert title URL into your browser to read the full article. Author:  John Allsop (G4YDM). Accessed on 05 January 2017, 05:35 hrs, UTC . Comment: John Allsop (G4YDM) has a fascinating website, which includes many interesting and simple projects that will enhance your enjoyment of Amateur Radio (see https://g4ydm.blogspot.com). In this article, John reaches back to a classic antenna design from the early 1920s which still produces amazing results in receiving signals on the standard broadcast band (medium wave) and on the 160 meter Amateur Radio band, a set of frequencies close to the upper reaches of the AM band .  This simple receiving loop can notch out noise and align itself for the best reception of broadcast and ham radio signals.  Radio amateurs who experiment on the often noisy 160 meter band will find John&
