How far apart should GPS antennas be?
Antenna separation: NMEA recommends three feet of separation between GPS antennas and most other antennas including VHF, cellular and Wi-Fi antennas.
Does pointing router antenna direction matter?
If you point all of you antenna straight up, the WiFi Router will be radiating the whole signal in a single direction. So for home WiFi routers with two WiFi antennas, it is always best to point one antenna horizontal and the other one vertical.
Does the Caddx Vista have a DVR?
One of the biggest downsides with the new VISTA air unit would be the lack of recording capability. It doesn’t have an SD card slot, and therefore you can’t record 1080p HD footage inside the air unit, you can only record footage in your DJI Goggles.
How do you power a DJI Air Unit?
The DJI Air Unit takes 7.4V to 17.6V voltage, you can power it directly from a 3S or 4S LiPo battery. However, I’d recommend powering it from an external voltage regulator, or a BEC on the FC. That’s because voltage spikes from motors and ESC could damage the Air Unit (same way it could damage your analogue VTX).
What is RxBT?
RxBT is just the “battery” seen by the RX – if you had telemetry from the Pixhawk you’d see the more interesting VFAS (but possibly only if you’re running off a real battery rather than USB – it’s unclear from what I’ve read). So the cell sensor clearly seems to be the telemetry addon to have.
Can you push a Nissan Leaf?
The Leaf was no more. If you need to push the car to safety, there’s no power steering. At this point, you may be wondering how long an extension cable you’ll need to plug into the nearest socket, but each Leaf comes with Nissan’s EV Roadside Assistance.
What happens when a Nissan leaf dies?
The Nissan Leaf, has a ‘Turtle Mode’ which is created when you run out of battery to push you to get an extra few miles before the battery completely dies. You can also buy battery packs in case you do run out, and that way you don’t have to pay the charge of a recovery vehicle and you can power straight back up.
What is Betaflight failsafe?
A failsafe is what the RC model does when connection or signal is lost between the radio transmitter and receiver. The common causes of a failsafe are: radio signal is out of range when you fly too far away. signal is blocked by obstacles. TX or RX is switched off, lost power or malfunctioning.
How far apart do TV antennas need to be?
The easy answer is that you should maintain a minimum mounting distance of at least 1/4 wavelength apart for the lowest frequency antenna within the same horizontal plane. For VHF antennas, that translates to roughly 19 inches.
Does aluminum foil boost antenna signal?
Older folks will probably remember the days of wrapping foil around their rabbit ear antennas to get a slightly better signal. But this technique still works with modern antennas as well.
Can two GPS antennas interfere with each other?
Separation between multiple antennas: If the antennas are installed too close together there could potentially be interaction between the antennas and a resulting loss of sensitivity. This could also adversely affect the search pattern of the antennas, resulting in fewer satellites being tracked.
Can two GPS devices interfere with each other?
GPS antennas are RX onlyunless they’re poorly designed or the feeds are poorly terminated, there shouldn’t be any issue with proximity to one another.
Can you mount a GPS antenna upside down?
If it gets a good signal in an upright position, flipping it upside down shouldn’t make a noticeable difference, if it’s a quality GPS. You can buy some new 3M mounting tape and put the tape on the top of the unit, then mount it next to your mirror.
How high should your router be?
For a two-story home, the best position will be located either near the ceiling on the first floor, or near the floor on the second, providing consistent coverage both upstairs and down. Radio signals travel best through open air.
Why do routers have 3 antennas?
Multiple antennas create several streams for sharing data over radio channels, which brings more bandwidth to your devices. Specs like MIMO and MU-MIMO increase a router’s capacity to transmit and receive data, which makes your network faster.
