tpms repeater

[bbaker2001]

Have the TST507 tpms system.
when traveling, not all the sensors show up. I have a 30ft 5er.
do I need to install a repeater, and are there different brands

If it taking that long for the sensors to come on line you definitely need a repeater or my preference an external antenna.

The sensors send normal update data about every 5 minutes.

^^^^^That seems to be pretty normal. I usually turn mine on when I first start tearing things down, and all of them are reading by the time we actually leave.

I also have the same system. I was loosing one of the signals a few times from one of the tires and called the company. They sent me the larger antenna to replace the small 1 inch one that came with the system. There is 6/8 feet of wire so you can mount the antenna just about anywhere in the truck. I have had the system for 5 or 6 years now and have not lost a signal since replacing the antenna. Its a 40' 5er and I mounted the antenna on top of the rear view mirror. I like it since you do not need power as with the repeater...

I have the 507 system. Am traveling now so will be on the look out for your 1 hour theory. Will post when I run into the problem agian.

It's not a theory, it is admitted to by the company when asked. And I have had it happen to me. The company says it's common practice but I'm not so sure of that.

Yes, please post back. Any and all information is wonderful.

Yes, alarm and no signal. But...don't think the signal is lost for an hour prior to the alarm, only because the readings change constantly up to the point of an alarm. Unless of course the readings I'm seeing are historical and being fed to me over time, but that seems unlikely.

The monitor takes about an hour to alert you to a lost signal. You will see the last reading until the alarm sounds, then the reading blanks out. You can check this by turning the monitor on battery power and leaving the trailer, like when you go get fuel or food. You'll find an hour will elapse before the alarm sounds.

What system are you using? If you're using a TST system, then an hour has elapsed before the beep. The last reading received from the sensor will be displayed until the alarm sounds. This takes about an hour.

Just curious how you know you've lost a signal? The alarm and no reading on the monitor? You do know that when the alarm goes off you've been without that signal for an hour. So if it reconnects within 20 minutes, you've essentially been without any contact with that sensor for an hour and 20 minutes.

FWIW if you lose a signal, and it reconnects before an hour you'll never know that you had lost the signal. A huge shortcoming with the TST system. The notifying time should be only a few minutes, an hour is ridiculous.

Have the same issue with my 507. I have the repeater but on occasion I still loose sensor signals here and there. All I do is shut down and start it up again. Call it a re-boot, all sensors come on line again.

I have the 507 and the 510 systems. 510 is for marine use so it's on my boat trailer. Before I go repeater route, I recommend you try to place the base unit up high. In my case the best spot on the 507 unit is the sunroof, passenger side (suction cupped) with the display pointed towards me. It's up high and in a clearer line of sight to the trailer tires. I now only lose a signal about every 1k miles and the signal comes back within 20 minutes on it's own. If you hold it up and the signal works, then consider a longer antenna before the expense of a repeater.

If you are losing signal at all on a TST system then you basically do not have a working TPMS.

Because of the one hour before a signal loss is reported them it is possible for a very large share of the time you will never know that a tire has failed.
