My amp/antenna build and distance test (I will update thread as i go)

[droneuser]

my thought is to put the passive relay on a pole 20 feet or so high! then the panel antenna ( amp in) would face toward the pilot that is on the ground! "theoretical" it should work!

I already have panels, amp , Omni antennas

Like your thinking, worth a shot.

Like your thinking, worth a shot.

ya its worth a shot I hope to run a few tests later this week with out the "pole" just to see if it will work

 

[droneuser]

well I my "secret" in today hum I am not very sure on this! lol I think the seller has it marked wrong! good thing it was cheap...lol

anyways windy now maybe later I will test and we will see how this works!

I will post results when I test

 

[Rnl]

Get on it

 

[droneuser]

ohh I will once the weather lets me now looks like rain but still to wind

 

[droneuser]

Well I did get some flight time in so the secret was going to be this 18dbi Omni antenna BUT

This being an 18dbi Omni antenna I was not very impressed with it ( I had that feeling when I saw it) but it was cheap and worth a try so to sum it up to date the 15 dbi antennas have a little more BUT not much and they being sooo darn tall I would recommend the 9 dbi antennas best bang for the buck and not tall like the 15dbi antennas!

here is the data WITH 4 watt amps the chart got cutoff BUT you get the idea

 

[droneuser]

next plan is to run a modded app BUT without the boost ( I don't want to overdrive the amps) I want to try different freq to see if it will help

not good to overdrive them it will make them heat up even more!

 

[droneuser]

as for the passive relay idea it has way to much db loss so back to the drawing board on that too!

 

[droneuser]

i may have to get this next not as good as the 600 BUT I think for shorter runs 30 feet and under it should be fine I was going to build a flight tower but this would be easier and cheaper in the long run I will use a pole that will "fold" down so I can change antennas if I want to

Well, a friend of mine a Ham Radio guy moved to town so he offered his 65 foot Aluminium self supporting antenna tower to me with a tip base. So I guess I will incorporate it into my Minnesota location I normally fly from a open field on our property but now if I install the antenna I can fly from my shop. I will mount a 4g yagi on it also for better internet in the shop also. I also have flown from our golf cart and drive around to different locations and have flown from inside my Polaris ranger cab with external mounted antennas before also.

 

[droneuser]

wow that's what I need!! a tower!! lol lol where in Minnesota ?

 

[mnoutdoors]

Central Minnesota north of St Cloud, have a cabin also up by the Canadian Border also where I fly but always on the US side

ahh ok ya St Cloud is about 3-4 hours away from me so your kinda close to my neck of the woods

 

[mnoutdoors]

So what neck of woods do you reside in?

 

[droneuser]

I am about 15-20 mins from La Crosse Wi if you know where that is at

Sorry to crash the thread... Are the antennas on the Mavic remote dual band or is one 2.4GHz and the other 5.8GHz?

I'm considering doing a control mod, but want to know if I need a 2.4GHz and a 5 8GHz booster or if I need 2x 2.4/5.8GHz dual band units. Thanks.

 

[droneuser]

nooo problem crash away they are 2.4ghz on the mavic however a dual band antenna will work to just make sure its NOT just 5ghz only!!!!

 

[GTMonster]

nooo problem crash away they are 2.4ghz on the mavic however a dual band antenna will work to just make sure its NOT just 5ghz only!!!!

Thanks... I was sure that the Mavic Pro could Tx and Rx on either 2.4 or 5.8? Is this not correct?

 

[droneuser]

yes mavic only tx and rx on 2.4ghz only when using the remote control
