Burton Brink, N6USO

I am a Advanced Licensed holder who loves using “HAM” radio from my Goldwing Motorcycle and anywhere else. My first Goldwing was a 1986 Honda 1200 Goldwing Aspencade with over 117,000 miles on it. I now have a 2002 Honda 1800 Goldwing that has my Kenwood 742 radio on it. I have been riding motorcycles since 1976, and have ridden over 400,000+ miles. It is one of the best feelings, riding in the wind.

I participate in many Charity events, such as the Baker to Vegas Challenge Cup relay race, Harley Davidson “Love Ride” (Muscular Dystrophy MDA), and Honda’s “Ride for Kids”, as well as many other Charity events.

I’m a major supporter of “HAM” radio as my Brother, KC6WVL/ Father, KC6WVM/ Wife, KE6SUW/ Father-in-law, W6NUN/ Brother-in-law KE6SUV and the most recent is my Son, Shawn, KG6TDG all have since received their “Ham Tickets”. My youngest, Tyler has shown an interest and hopefully will get his soon.

I Belong to The Goldwing Road Riders Assoc. Chapter I Covina (GWRRA-Life Member), Blue Knights Law Enforcement Motorcycle Club CA-IV (Charter Member), Motorcycle Amateur Radio Club (MARC) and many other groups. I am also a Member of the Family Motor Coach Assoc and the Good Sam Club. I enjoy camping in motorhomes and also have a ham radio in our family’s motorhome.
I am the OWNER/LICENSEE of the 145.440- (136.5 Tone) 2 meter N6USO repeater on Sunset Ridge located at 5300+ feet in the Angeles National Forest of Southern California,by Mt Baldy. http://www.n6uso.com for infomation on the repeater. It has many links and a daily NEWSFEED on Ham radio. The repeater covers most of Los Angeles, Orange, San Bernardino and Riverside Counties.

I am a Deputy Sheriff for Los Angeles County Sheriff’s Department and in a Law Enforcement Officer since 1982. I am presently assigned at Temple Sheriff’s Sation since 1992, was assigned as Field Training Officer from 1997-2000. Now I’m a Motor Officer since 2000 and a Motor Field Training Officer/Dept Motor Instructor and Presidential/Dignatary Motor Escort Deputy. I started the “HAMWATCH” program at Temple Station in 1993 and I am a member of “D.C.S. Disaster Communications Service” with Los Angeles County Sheriff’s Dept (Have to I work there).

My wife Gerie, KE6SUW is a personal trainer at Bulldog Gym in Glendora and a “Spinning Instructor there. She has been a Personal Trainer since 1997. We have 2 sons, Shawn KG6TDG and Tyler.

The above picture was taken on Glendora Mountain Road (So. California) for a magazine called “Wing World” from the Goldwing Road Riders Assoc. This Picture was featured as the full page calender of the magazine in September 2002. Another picture taken there was featured on the cover of their yearly (2003) “Gold Book” for the group, identifying all it’s world wide members as you travel for assistance or information in the area you are traveling through.

Yagi Antennas Explained

Some of the Yagi antenna theory can be complicated, but a basic understanding of how a Yagi antenna works can be given sufficient for design purposes.

The different elements of the Yagi antenna react in a complex and interrelated way to provide the overall performance.

In order to be able to develop a Yagi antenna it is necessary to have at least a basic understanding of the Yagi antenna theory.

Yagi antenna theory – the basics

The key element to the Yagi theory is the phases of the currents flowing in the additional elements of the antenna.

The parasitic elements of the Yagi antenna operate by re-radiating their signals in a slightly different phase to that of the driven element. In this way the signal is reinforced in some directions and cancelled out in others. As a result these additional elements are referred to as parasitic elements.

In view of the fact that the power in these additional elements is not directly driven, the amplitude and phase of the induced current cannot be completely controlled. It is dependent upon their length and the spacing between them and the dipole or driven element.

As a result, it is not possible to obtain complete cancellation in one direction. Nevertheless it is still possible to obtain a high degree of reinforcement in one direction and have a high level of gain, and also have a high degree of cancellation in another to provide a good front to back ratio. The Yagi antenna is able to provide very useful levels of gain and front to back ratios.

To obtain the required phase shift an element can be made either inductive or capacitive.

  • Inductive:   If the parasitic element is made inductive it is found that the induced currents are in such a phase that they reflect the power away from the parasitic element. This causes the RF antenna to radiate more power away from it. An element that does this is called a reflector. It can be made inductive by tuning it below resonance. This can be done by physically adding some inductance to the element in the form of a coil, or more commonly by making it longer than the resonant length. Generally it is made about 5% longer than the driven element.
  • Capacitive:   If the parasitic element is made capacitive it will be found that the induced currents are in such a phase that they direct the power radiated by the whole antenna in the direction of the parasitic element. An element which does this is called a director. It can be made capacitive tuning it above resonance. This can be done by physically adding some capacitance to the element in the form of a capacitor, or more commonly by making it about 5% shorter than the driven element.

    It is found that the addition of further directors increases the directivity of the antenna, increasing the gain and reducing the beamwidth. The addition of further reflectors makes no noticeable difference.

In summary:

Reflectors – longer than driven element = Inductive
Directors – shorter than driven element = Capacitive

Another Test News Item

This is just another test news item. It is a long established fact that a reader will be distracted by the readable content of a page when looking at its layout. The point of using Lorem Ipsum is that it has a more-or-less normal distribution of letters, as opposed to using ‘Content here, content here’, making it look like readable English. Many desktop publishing packages and web page editors now use Lorem Ipsum as their default model text, and a search for ‘lorem ipsum’ will uncover many web sites still in their infancy. Various versions have evolved over the years, sometimes by accident, sometimes on purpose (injected humour and the like).

Sample News Item

This is a sample news item.  When we have real news to share, we can delete this and add a new item.  We can keep adding new items… the newest ones will always be at the top, and old ones will float to the bottom, or to a separate page.

News items can have pictures. Notice how I’ve set a featured image for this post.  We can add additional pictures, too, by using the “add media” button.

That completes this sample news item posting. I hope you enjoyed it.
