The Annual Mobile Shootout

Shootout Master - Lon Martin, K0WJ

Mobiles—this one's for you!  For those new to the idea, every year at our Eyeball gatherings, we hold an event called the "Mobile Shootout."  The purpose is to give all entrants an idea as to the effectiveness of their own mobile installations.  Having an effective mobile setup takes more than just slapping an antenna on your bumper and connecting it to a radio.  So who are the big guns on our nets?  Better still who is the "Top Gun?"  We all have our opinions, but the Shootout will actually measure each mobile's signal strength, and when the smoke clears there will be only one wearing the "Top Gun" hat.  Will it be you?  See RESULTS of past Shootouts below.

If you're new to mobile operations, the day before the actual Shootout, Lon, K0WJ, will conduct a "Mobile Clinic" where he will show you, based on his personal experience, how you too can have a highly effective mobile installation.  If you want a head start on the tips that will be presented on the "Mobile Clinic," please visit the links below, especially the K0BG web site, and follow the examples found there.  It will take you some time to get through the K0BG website, but it's all there.

Who has the most powerful signal down range is controlled by a number of things that go to make up the total "Mobile System."  The "Mobile System" includes the antenna itself, the vehicle it's mounted on, the mounting location on the vehicle, the quality of grounding, etc.  The Mobile Shootout provides a measurement of ALL these factors combined in the form of a signal strength measured down range.

Each mobile operator will drive his/her vehicle to a designated test range where, after the operator is satisfied that the antenna is properly tuned, officials will attach the mobile antenna to the official contest RF test source—one that will put out a consistent 10 watts of RF (as measured by an inline Bird wattmeter) on the specific net frequency chosen for the shootout.  At the receive site, located up to several wavelengths away, as space allows, each mobile's signal strength will be recorded.  When all participants' signals have been measured, the results will be calculated, with the winners announced and prizes given out at our annual awards presentation ceremony.

Remember, unless special categories are announced, the Mobile Shootout is for street-legal mobile setups, so the highest point of the antenna must be no higher above ground than what is legally allowed on public roads and highways—no more than 13.5 feet high at the highest point and no more than 8 feet wide, including any capacity hat.  If you can build a roadworthy, 8-foot diameter capacity hat, you can enter it.  Besides we'd all like to see that one.  We will measure!  The antenna system as a whole must be roadworthy.  You must be able to drive in and out of the contest area with the antenna installed and must also be able to operate at highway speeds.

All objections and concerns any contestant may have must be verbalized during the Shootout and disputes will be settled by a majority decision of the people at the Shootout site with Lon, K0WJ, acting as the moderator.  Objections and concerns voiced after the fact will NOT be considered.  The purpose of the Mobile Shootout is to gain insight into what it takes to improve our mobile signals, and to have fun.

Our thanks and gratitude to Tom Bates, AA1NZ, Shootout Master Extraordinaire.  Tom is the creator of this event that so many have enjoyed, and he was the driving force behind it for Eyeballs 2002 - 2009.  Lon Martin, K0WJ took over as Shootout Master effective with Eyeball 2010.

At Eyeballs 2011 thru 2014, Lon Martin, K0WJ, conducted Mobile Antenna Clinics aimed at helping members improve the efficiency of their mobile antenna installations.  His presentation is available in both PDF and PowerPoint formats.  For those wanting full-page slides, look at Mobile Installation Clinic Slides (PDF file, size 4.9MB).  This same material is available with half-page slides plus added notes at Mobile Installation Clinic Notes (PDF File, size 2.5MB), or as a PowerPoint Presentation (slides only) at Mobile Clinic (PPT File, size 118MB).

Potential Shootout entrants may also wish to look over the Mobile Operators' Web Site.  Alan Applegate, K0BG, is renowned for his insight and knowledge of mobile installations.  If you follow the suggestions made by K0WJ and K0BG you'll have a much better chance of competing.


Mobile Shootout Rules

The Eyeball Mobile Shootout requires you to use your own transmitter as the RF source.  Because of this, you will need to know how to operate your rig to produce a continuous unmodulated RF transmission and you will need to know how to adjust the power level of that transmission to a predetermined wattage level as indicated on a wattmeter that will be supplied by our Rangemaster.

Rules for Shootout 2015 will be:
