VIDEO 1: Installing a motorized HF antenna.

[Video viewing instructions: When this page first appears the player screen will look black. You do NOT need to click the "play arrow" right away, wait until a still image appears and then click the "play arrow". There is sound with the video so turn up your speakers! Please be patient as on a high speed internet connection (e.g. cable modem) this takes 3-5 minutes for the image to load as the file is approximately 18 mb in size. You might want to read the story below while the file is loading, get a cup of coffee or try for a rare DX station!]

This video shows the black anodized version (Series 11) of the UHAM-100 antenna mount and the optional second antenna mount (SAM-100). The bare aluminum version (Series 12) is identical in every way exept for the finish. Please note that the Series 11 has been replaced with the Series 14 with powder coated paint in any of 5 standard colors. All other specifications and performance are the same and accurately portrayed in the video.

You can see how quick and easy it is to install even the large Hi-Q Antennas "5/160" motorized HF antenna with a 5" diameter coil. The mount also fits the motorized "screwdriver" HF antennas made by other manufactuers up to 2-1/8" diameter at the base of the antenna (does NOT matter how large the antenna coil is). For some screwdrivers such as the High Sierra 1800 that do not use a standard 3/8" bolt  you can use their quick release base stud or the antennas can be mounted without the stud, using a 3/8" stainless steel hex bolt. There is a 3/4" diameter hole in the 3/4' thick portion of the UHAM-100 that allows installation of your brand of antenna.

It takes approximately 20 seconds to install the antenna. You can see how sturdy the UHAM100 is in the video: when the antenna is pressed down hard against the mount to "lock" the optional quick disconnect (the one in the video is the GQD by Hi Q Antennas) the entire car suspension moves down but the mount does not bend! The car in the video has a stiff suspension by the way! The base of the mount is very sturdy, and is made of 3/4 inch thick solid 6061 aluminum.

The setup shown in the video allows me to operate, with the two antennas shown, from 6 to 160 meters with a capacity hat 12 inches above the loading coil. With this setup I am able to drive into my garage which has the standard, rather low, garage door heighth. I use a duplexer to connect the two antenna coax feeds into the HF antenna jack of an Icom IC-7000 transceiver.

The antenna in the video is a Hi-Q Antennas model 5/160RT motorized HF antenna with a 5-inch diameter loading coil and capacity hat. This is one of the largest motorized HF antennas currently on the market, and it works great and is very stable at HIGH highway speeds, without the need for guying to a roof rack. I have installed the optional Hi Q Antennas "GQD" quick disconnect, which will fit other brands of antenna that use a 3/8x24 "set screw stud" at its base. The GQD is visible in the video, and can readily be seen in the early part of the video before the antenna is installed.

The second (smaller) antenna behind the screwdriver is a multi band HF-VHF-UHF antenna (OPEK HVU-100) that I use only as 1/4 wave (aprpoximately) 6 meter antenna mounted to the optional second antenna mount ("SAM-100"). 

Happy DX!
