It was good to get back behind the wheel of my 2005 Toyota Tundra – although can’t say I am excited about paying to fuel it up. I’ve attempted to get a good HF install for mobile operations before experiencing limited success… with perhaps my biggest rookie mistake being an attempt to use the ICOM AT-180 autotuner along with my IC-706MKIIG.
I used Hamsticks and Hustler mono band resonators – it worked pretty well but I got tired of having to exit the vehicle every time I wanted to change bands.
My answer was to install a screwdriver antenna. I’d been planning this mobile install for some time, using lessons from my trials in the Spring of 2007 as well as a significant amount of reading and research (eHam, WorldRadio, CQ Magazine, websites). I decided on basing my mobile install around the Tarheel Model 75 “Stubby” providing continuous coverage from 3.7 to 34 MHz. The folks at Tarheel worked with me to get me going – responsive to my emails and questions.
The radio for this mobile install: my ICOM IC-706MKIIG. I’d originally purchased this radio when I arrived in Hampton back in the early Summer of 2005. The purchase was in part to motivate me to upgrade from Tech to General – which it did. That Summer I passed the written exam (Element 3) at a nearby hamfest for General. But I was not yet ready for the Morse (Element 1). It wasn’t until later that Fall that I was ready for the Morse… and barely passed too. I’ve been very pleased with the IC-706MKIIG; it is a great radio for a beginner, easy to operate, solid performance, flexible to use either in the radio shack, portable, or mobile.
To mount the antenna to my Toyota Tundra, I really did not want to permanently mar the exterior of the truck. I’d admired K4GUN’s install and thought his implementation of using the Geotool stake pocket on the bed of the truck was brilliant. I wrote Steve, K4GUN, concerning his install and he provided some great additional information concerning the challenges of the stake pocket mount. After working with Rick, WA6JKH, to ensure I was ordering the proper mount, I placed my order and Rick gave me a nice active duty military discount.
I decided to get N2VZ’s Turbo Tuner for ease of operation. Operating HF while driving is already complicated enough and I wanted to make tuning the antenna as easy as possible. Bill was very responsive and also provided a military discount.
I had ordered all the equipment while in Iraq, so everything was waiting for me when I arrived home.
The install took two days. Perhaps the hardest part was mounting the IC-706MKIIG under the passenger’s seat. Already installed under the seat was my ICOM IC-208H – my trusty VHF/UHF rig. I’d originally installed this rig during my circumnavigation of the continental US back in 2005. During that install, I only partially removed the passenger’s seat. This time I pulled the seat completely out of the truck which greatly helped me successfully position both the IC-208H and the IC-706MKIIG in the limited space.
Routing the feedline from the rig to the stake pocket mount was fairly easy, making use of the rubber grommet directly under the passenger’s seat and zip ties along the feedline’s path to the rear of the truck. Soldering the connections to the stake pocket mount was straight forward but it was a bit tricky feeding the line up through the bottom of the stake pocket.
Setup of the Turbo Tuner was a snap; I followed the provided instructions step-by-step, making sure I had the DIP switches positioned properly.
Mounting the antenna onto the Geotool stake pocket mount was made easier by using the HI-Q’s Giant Quick Disconnect. Payment was via PayPal and Charlie, W6HIQ, had it on my doorstep within the week. Thanks Charlie!
How does it work? So far, so good. More reports from the road are coming… and maybe a picture or two.
