antenna question

[brunoferreiro]

I know are a lot of post about this, but only about distance performance.
I have a question, you all in most cases replace their antennas with directional antennas such as alpha or FPLV. But always looking for power and great flight distance. If I want some more signal strength flying nearby, but I want to overcome obstacles such as buildings or trees for one orbit, is not it more convenient to use an omnidirectional antenna of 11dB as alpha omni?

I have at this time 2-alpha 10dBi directional antennas. And if I am constantly following with the control at the drone, radically lower the signal to make an orbit, or multi cam.

i was thinking in something like this:

TOTOLINK A011KIT - 2 Indoor/ Outdoor 2.4GHz/ 5.0GHz 11dBi High-Gain Omni Directional, Wide Signal Coverage Wi-Fi Detachable Booster Antennas for 802.1

As I understand it, you're looking for something to "burn through" buildings and obstructions. I honestly think that, as far as standard antennas go, the FPVLR will be better at this than an omni.
Seems to me you'd be best off simply installing a booster/amp. I have one of these but haven't used it yet - but everyone says they're great (that's why I bought it!).

yes, I want that, and not necessarily to be all the time pointing to the drone not to lower signal strength. If I combine my idea and yours? With 11dB omni antennas booster?

black and 4 more dB.

Not sure how the setup you mention would be, but I can say the fpvlr setup gives you much better signal, penetration, and video quality. Honestly since the newer updates my stocks are even much improved, but the fpvlr is great as a go to in situations like you describe. I'm pretty careful usually, but do fly beyond obstructions some and haven't lost signal once since I bought mine in June.

If he goes with a booster though he'll want 2.4ghz as opposed to that 5.8ghz model.

Isn't it the 2.4GHz that we need?

Yep, that's right.... I pasted the wrong link in there. Principle remains the same though!

Some antenna feedback. Antennas didn’t’ help for me. I have bought 4 different antenna’s which were successfully used by other people but my stock antenna’s would still perform better than any of these 4:

I haven’t tried the FPVLR so I can’t tell how they perform. I am very tempted to give them a try though but currently my priority goes to the 3.97 mm lens from PEAU http://www.peauproductions.com/products/gp39728


Following is doable but not recommended though:

If you really want to go behind obstacles, 2.4 GHz isn’t a good frequency to use. You can either change to UHF ( but this will be a big mod so I wouldn’t do it) or stay on 2.4GHz and use Tower to be able to plan a mission where you know you are going to lose signal but the mission will continue despite losing your TX signal. Keep in mind that you will lose you VIDEO at this point till you recover LOS. This is done by changing the failsafe parameter FS_THR_ENABLE from the default “Enabled always RTL” to continue mission when in AUTO mode.

You have to be very familiar with Tower to do this and practice several missions so you fully understand how this works.

Good luck with your antenna search.

It's on my wishlist.

Word of advise when you look for higher gain antennas you will see they advertise higher gain antennas and they give two frequency bands, 2.4 GHz and 5GHz values with one level of rating, in this case 11 dBi. Make sure you check the full specs and fine print because most of the time the higher gain level of power that they advertise (11 dBi) is for the 5GHz band not the 2.4 GHz band which most likely be 8 or 9 dBi. These are dual band antennas not single band antennas. Solo works out of 2.4 GHz ONLY, so 5GHz will do noting for you. Don't get me wrong they still work fine because they transmit both bands simultaneously (read my earlier post here there is more detail specific details there What is the real deal with the antenna orentation?). I have been researching and experimenting on different types of antennas and if you are on a budget they work better than expected. I suggest you read my post and check out the video links you will get a better idea on how they work and what to do.
