Hawaii County Mayor declares Amateur Radio Week in Hawaii County. Post #281.S

Source:   Hawaii Tribune-Herald , 14 June 2014. Reporter:  Bob Schneider (AH6J), ARRL Pacific Section Manager. In tribute to Hawaii Island hams who provide emergency communications for Hawaii County during times of natural or man-made disasters, Hawaii County Mayor Billy Kenoi has declared 23-29 June 2014 as "Amateur Radio Week" in Hawaii County.  Mayor Kenoi has urged the public to support the American Radio Relay League 's (ARRL) Field Day events set for Saturday, 28 June 2014, when amateur radio club members will set up and demonstrate emergency communications equipment and skills. In Hilo , the public is invited to activities hosted by the Big Island Amateur Radio Club (BIARC) from 8 a.m. to 5 p.m. at Walmart.  A Field Day station will be operational from 8 a.m. Saturday until 8 a.m. Sunday at the Wailoa Visitor Center in Hilo.  During that 24-hour period, local ham operators will contact other amateur radio operators across the Pacific and North America.

Simple Ham Radio Antennas. On the ground antennas. Post #280

Over the past few weeks, I've become fascinated with antennas mounted on or near the ground. I've even built a few, such as Mike Toia's (K3MT) "grasswire" antenna and a similar "earth" antenna from Australia.  A few months ago, I built a simple beverage antenna for my old Hallicrafters SX-62A receiver.  All or these wire antennas worked very well, especially for the AM broadcast band . With a few modifications, these wires can be used as a separate receive antenna for amateur radio stations located in noisy or desert areas.  I've used vertical antennas for transmitting and low-mounted antennas for receiving.   So, what are these ground hugging "long wires?" According to articles published in the "NASWA Journal" for December 1992 and January 1993 by author Joseph Buch, these antennas mounted on, near, or slightly below ground level are called "wave" antennas because "they extract energy from the wave as it tr

Simple Ham Radio Antennas: The "Down To Earth Antenna." Post #279

Are you looking for an inconspicuous amateur radio antenna that is largely invisible, yet delivers acceptable DX and local results?  An antenna idea described by Robert McGregor (VK3XZ) and published in the May, 1993 edition of " Amateur Radio " (Australian magazine) may suggest a few alternatives for hams facing restrictive HOAs and CC&Rs. A few weeks ago, Dean Manley (KH6B), gave me a copy of this fascinating article for my antenna reference library.  I've built several disguised antennas, ranging from K3MT's "grasswire" antenna to low-lying dipoles running just above my home garden.  But none of this antennas worked as well as "The Down To Earth Antenna" from Robert McGregor (VK3XZ). Here are some pertinent paragraphs from Robert's article. DOWN TO EARTH ANTENNA Australia and the African Desert have a common need for radio communication and a mainly sandy terrain. VK5TL's letter, AR Jan. '92 caused me to dig deep into a

Simple Ham Radio Antennas: The Aluminum Foil Vertical. Post #278.

I knew it would happen.  The time I ran out of antenna wire.  After several years of using old #14 AWG house wire, #18 AWG speaker wire from Radio Shack , and remnants from studio wiring projects at my former employer (Pacific Radio Group), I had finally exhausted my wire supply for homebrewed antennas.  What to do until the next sale at Lowe's, Home Depot , and Ace Hardware?  Give up? Banish the thought!. With last week's beautiful weekend before me, I needed some cheap wire to erect my latest antenna "masterpiece."  I found my resource in the kitchen in the form of a new roll of "Diamond Aluminum Foil"--the stuff my xyl uses for cooking tasty treats and dinners.  Since there were several new rolls near the stove, I decided to "borrow" a new roll and apologize later.  Besides, I would buy another roll the next time I visited the supermarket. According to the label on the container, the roll contained 66.66 yards (199.98 feet) or 60.96 meters

Simple Ham Radio Antennas: An Extended Double Zepp for 20 meters. Post #277

How would you like to have a simple dipole-like antenna that would give you almost 3dB over over the classical dipole antenna ?  You can if you're willing to build a Double Extended Zepp antenna for your favorite amateur radio band.   Now that I have enough room at my new home-in-progress in the Puna District of Hawaii Island, I decided to make a simple gain antenna for one of my favorite DX bands--20 meters. I had a spare MFJ telescoping fiberglass mast available, some leftover #14 AWG house wire in the garage, a spare 4:1 W9INN balun, a 50-ft./15.24 length of 450 ohm ladder line , a sturdy Drake MN-4 transmatch ("the tuner"), and 25-ft./7.62 meters of RG -8X coaxial cable with UHF connectors. I decided to configure the extended double zepp as an inverted V, knowing that its gain would be a bit less than a horizontal arrangement of a half wavelength dipole. With school over until mid-August, I thought this simple antenna project would give me something creat
