Oldguy Posted June 24, 2016 Report Posted June 24, 2016 Now with my ADS-B Out, I get TIS-B traffic and am wondering about the value of my ATD-300. It always does a good job of letting me know when another plane is taxiing by me when I am on the ground, but other than that, I have never heard it make a sound while flying. It's not a lot of weight, just another antenna and more draw on the electrics. Don't get me wrong, I understand the limitation of the TIS-B traffic, but wonder at its usefulness regardless. I would enjoy the redundancy if I felt it was showing anything , but yesterday at 79J, there were three Army choppers, one V-tail Bo and another 201 within a 1/2 mile of me and I heard nothing from it. It has the single antenna on the bottom of the plane. Is everyone else using an ATD-300 getting any alerts, or is it something I should consider taking down at this time? Quote
TWinter Posted June 24, 2016 Report Posted June 24, 2016 Not sure if yours is working properly or not, but I think it was AOPA mag last month that said only 20% of the planes flying are ADS-B compliant already. Now since they are considering the idea of some rebate money for future ADS-B installs ( I don't know if that is a done deal or not?) some owners are waiting for that to happen and have said to be cancelling or pushing their ADS-B installs up to wait for the rebate money. You already own the 300, it's relatively compact and it's not the year 2020 yet. I say hang on a while longer if it is working correctly. Never hurts to have that extra insurance.

LANCECASPER Posted June 24, 2016 Report Posted June 24, 2016 "Piloto" on Mooneyspace (Jose Monroy) developed the ATD300. Maybe he'll chime in and discuss the benefits of active traffic. My thoughts are if it's in there why take it out? 2 Quote
Piloto Posted June 25, 2016 Report Posted June 25, 2016 If you fly in non ADS-B coverage areas the ATD-300 or a TCAS systems are your only options. Unlike ADS-B/UAT the ATD-300 will alert you on the ground of Mode A/C traffic in the pattern that ADS-B can't. I found this very helpful at uncontrolled airport. Unlike the ADS-B products that requires a tablet or a separate display the ATD-300 has its own display. This eliminates the interface compatability problems and gives more options for installation. BTW it is easier to read the ATD-300 larger display than on a G530. Oldguy try turning ON the ATD-300 after the avionics master is on. Some planes generate spikes that can affect the ATD-300 self protection and shutdown the bias voltage to the antenna (ANT-300). This causes the ATD-300 to only see nearby traffic. The problem is not noticeable with the portable or transponder type antennas. More info at: http://www.monroyaero.com/ATD300Webpage8.pdf José 2 Quote

I have the ATD on the avionics master which I turn on after starting the engine. Quote

If the ATD-300 is connected to the ANT-300 it will not show far away traffic or it will not indicate traffic direction for traffic nearby. The spike transient is caused by the onboard avionics during power up of the avionics master. José Quote
carusoam Posted June 25, 2016 Report Posted June 25, 2016 We have a few military jets flying around NJ. Transport type more than fighters. My SkyRadar ADSB in doesn't seem to notice them... Guessing they are not sharing their Transponder with us. Best regards, -a- Quote

The ATD-300 was in my plane when I purchased it and is panel mounted, powered through the avionics switch and attached to the ANT-300. Next flight out, I will pull the breaker it is on before I power up the avionics switch and then reset it. From everything you have said, it appears the spike transient may be my issue. Thanks a bunch. Quote
