During the flight the graph developed over time, flight events, accelerations & altitudes were read off the developing graph and relayed via FRS radio to the LSO for broadcast on the PA and local FM radio system.

The AltAcc was used to control the flight for this test because the R-DAS resided in the ATV payload compartment at the top of the rocket (see photos below). Gee differences after drouge and main deployment are due to the different physical orientation of the units. Difference in total decent times are because the AltAcc and R-DAS units were under separate main chutes.

Inverted V dipole constructed of piano wire with internal solder lugs, supported by the body tube and main board.  
The inverted V is a balanced antenna and has a more uniform radiation pattern which is directed somewhat toward
the ground.  RG-174 coax (50 ohms, 1/10 inch diameter) connects the antenna to the transmitter board.  Larger "regular size" 
coax can be used if weight is not much of a consideration.  Large hole is for the television camera (not in use for this test...
....see http://www.vahpr.com/atv/atv.html for some ATV details and video).

A challenge in receiving TV and telemetry payload signals is that they are affected by the rotation of the rocket around its axis. The rotation of the transmit antenna aboard the rocket can affect how well the signal is received on the ground, particularly when the rocket is at higher altitudes. To obtain maximum received signal strength, the transmit and receive antennas need to be in alignment (or in phase). Since we can't keep our rockets from rolling (yet), we have to engineer the receive antenna to keep the signal from fading in and out.

One solution is called a turnstile antenna because it has two sets of elements crossed at 90 degrees. As the rocket rolls the signal received by one set of elements will start to fade, but at the same time it will increase in the other set of elements. Connection of the two sets of elements is made with a specific impedance of coaxial cable cut to a certain length. This causes the signals from both elements to add together and the output is relatively constant regardless of the payload orientation to the antenna. Aluminum screen or a metal plate placed at a certain distance under the crossed elements reflects some of the received signal back, which gives the antenna some directionality. These types of antennas have some gain and receive well over a fairly wide arc of sky without having to be realigned. They are also easy and inexpensive to build.
