DVB-T2 Finder 4+

No need to search on the internet, no need to study tables, no need to ask the neighbour, just start the app and run QuickCheck. After 30 seconds, you will know whether the purchase of a DVB-T/T2 receiver and antenna will be worthwhile. And what channels you will be able receive!

# QuickCheck
The QuickCheck searches for all DVB-T/T2 transmitters in your area, calculates the distance, and analyses the geographic features between the transmitter station and the receiver. With this data and the parameters of the transmitter system (frequency, transmission power, horizontal/vertical emissions, height of the transmitter mast, etc.), the reception field strength is calculated at your location and a user-friendly forecast in plain text is created from the data. Antenna characteristics are still not considered in the QuickCheck (since you probably still don't have an antenna).

You will also receive a recommendation for the right transmitter location.
Select this location under Transmitter.

#Transmitter
The Transmitter menu gives an overview of all installed DVB-T/T2 transmitter locations. The transmitter locations are sorted by distance to your location. If you select a specific transmitter, you will receive an overview of the technical data of the transmitter (multiplexer, channel, etc.) and the channels offered by the transmitter. (The icons for HD channels are framed in red.) The transmitter selected in this menu is the basis for the Antenna and Align menu items.

#Antenna
This menu lists different DVB-T/T2 antennas. For the first two antennas (1/31 and 2/31), you can configure the amplification factor specified in the antenna data sheet yourself. Antenna 1/31 is an indoor antenna and antenna 2/31 is an antenna for outdoors. The amplification factor (and other parameters) are already pre-configured for all other antennas. Now select an antenna and start alignment.

#Align
You can use the pointer instrument (above) under Align to assess the signal strength. However, a high signal strength is not synonymous with high reception quality. You can visually judge the reception quality in the lower display. An ideal signal has the shape of a bell curve. Many small spikes in the signal shape indicate a high noise component and thus a worse reception result. Now try turning the iPhone to optimise the signal. Also test other receiving antennas under Antenna.

# FineTuning (for outdoor and roof antennas)
You can further optimise the reception of your antenna system as needed. The DVB-T2 finder provides the FineTuning function for this. You need a second iOS device to use this feature. A device serves as a camera; the second device as a monitor. Simply place an iPhone in front of your receiving screen and observe changes in image quality as you gently tilt or incline your antenna. With the FineTuning function, you can thus have see how the reception changes on your TV, even if you are not in front of it.

# Simulation of the reception situation at other locations
If you would like to know BEFORE your camping holiday whether bringing a DVB-T receiver would be worthwhile, you can check this location out in advance. Go to QuickCheck menu and tap on the small gear icon in the upper right corner. There you will find Change Location. Activate the switch and activate the map display by tapping below the GPS switch, select any position, and run QuickCheck again.
