My only beef is the unit’s inability to tune a balanced antenna. Weather resistant The AT is housed in a durable, completely weather-resistant acrylic case with rubber gaskets. Usually closer to 2. I repair marine electronic equipment for a living, so I have the advantage of being very familiar with this unit. For a new frequency, it takes between 2 and 10 seconds. Getting the AT to autotune when it sees a new carrier seems impossible. The main benefit of the ‘ is cost. Should be a interesting experiment.

Use a choke balun to reduce shield radiation. No manual tuning is needed. Reviews Summary for Icom AT Just connect the control cable and antenna wire and go! It seems to be a bit st130 rugged than my AH-4, which I toasted by trying to tune a 75 meter mobile whip kcom 40 meters.

Normally 8 Volts, when less than 1 volt is recieved a tune cycle will commence”. Getting it to play with non – Icom radios is possible, but probably not in a fully automatic sense.

As its a commercial unit and unlikely to be connected to a non-icom HF set, I can see why this has gone undetected. This line needs to be connected to your radio in a way that causes it to go into the transmit mode, and produce about 10 – 15 watts of rf – NOT full TX power!

I’m limited as to the amount of RF i can put through it but watts is OK for me ag130 as i said i have a balanced antenna i just connect the open wire feeder directly to the atu, one leg of the feeder to the hot side and the other to the ground, and a common mode choke at the feed point between atu and transceiver.

This allows you quick trouble-free frequency changes.

Unacceptable in a marine HF system. No problem in tuning a long wire. The versatile AT can be used with a variety of vessels, even smaller boats that cannot use a long antenna element. The AT emits very little output power just mW during the tuning process. This reduces the possibility of causing interference to other att130 using the frequency. It has accompanied me to at least two different ships to be used with ta130 wire antennas.

When tuning the same frequency twice, it is all over in less than a second.

AT installation is simple. It only takes a couple of watts of RF to figure out what to do.

The AT allows you to transmit with strong RF output power, and is perfect for maritime mobile operations. It works great that way.

You have to manually start the tuning process for any new frequency. What it really means is “ground this input if you want it to start tuning”. In addition, the AT has 8 convenient memories to store tuning information.

Low power tune-up The AT emits very little output power just mW during the tuning process. One drawback to using the AT with the is that every time I would change bands or frequency ranges the st130 would automatically tune. I recently got my brand new AT working. Give it a better than average ground. I purchased the unit while I was on holiday so I’d be forced to read through the manual for a few days at103 trying to hook it up. It is a capable tuner if you observe the following measures: By design, it wants to end feed a random wire.
