Screwdriver Antenna Memory
Product Information Sheet
Product SummaryThe Screwdriver Antenna Memory (SAM) is designed as an addition to the class of mobile HF antennas referred to as the "screwdriver" antenna.
The tuning of this antenna (after initial setup) is usually done visually by holding the motor switch while watching the antenna followed by fine tuning by SWR or "ear". Most users put a strip of tape or use some other method to "mark" the "general" location for each band. The SAM will replace these visual markers with an electronic one.
The SAM replaces the "control panel" which you currently use to tune the antenna. It contains a VFO style tuning knob as well as a push button. The new control panel also contains a dual digit display to give the operator visual feedback as to the current SAM setting or memory channel. The size of the SAM box is (2"H x 4"W x 4"D)
The unique feature of the SAM is the VFO style tuning knob used to 'fine tune' the antenna. The knob is also used to select the memory presets.
Using the SAM
In memory mode, the tuning knob will be used to select one of 16 preset memory locations. You simply turn the knob until the LED display shows the desired memory number. Then, once you have the correct memory selected, you just press the tuning knob (The knob is also a push button) and the antenna will automatically "re-tune" to the preset location. Once you recall a saved setting, the antenna will return to the preset location. You may then use the "jog mode" feature which allows you to adjust the antenna from that point for "fine tuning".
While in the Jog Mode, the LED display will change to help indicate
the operation being performed.
Fast Jog Mode
InstallationThe requires you install a small magnet clip onto the main screw shaft inside the antenna. This is done by sliding the coil, shaft and motor out of the outer tubing and clipping the magnet assembly onto the main screw shaft or motor. You then will mount a small sensor on the outside of the lower tubing section. This can be attached by two small screws, JB Weld or RTV silicone glue. If you are unsure if your antenna can be updated to work with the SAM you can check our "Sam Ready" list. The manufacture of your antenna may be able to help on how to install your sensor.
