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

[droneuser]

You've seen beanbubbas he did it for a reason.

yes I did see some info on that I haven't read the whole thread....lol to see the reason yet

 

[droneuser]

Of the 8 watt (5W ) (depends on who you buy them from ) (they appear the same )ones I’ve tested (6) they all will output more than the black amps called dragon amps (4W) ( if you look at them it looks more like a dove than a Dragon) now they both gain from the RC controller as a product of time ( the RC increases over time) in most cases they will get 2.5-3watts over the dragon-dove amps. 3watts more than say 36dbm on the dragon-dove amps in one test I have tested 42dbm I use both, and have been pleased with both, the bigger ones cost more.about 15 dollars more if you shop around

yea I see the 8 watt ones are 40 plus each BUT the 8 watt ones have a very good RX!!! I may have to get one!! lol

@mnoutdoors @Rnl ask about your panel antenna if you miss that post

 

[Rnl]

Where are you finding those amps.

 

[droneuser]

ebay i will have to find the link

 

[mnoutdoors]

I have posted all of it before, I have 7 different panel setups the biggest are 20dbi they will get the farthest.
But the cheap china ones are close behind at 14dbi modified (removed the cords)I have a dragon-dove amp on one set and the 8w on another.ITElite Max panel with 8watt amps 14DBI, Titan amped panel, the small itelite with sunhams amps. And one more set of 8w amped 14dbi with 14dbi yagis at the same time

 

[Rnl]

Yea, you got it covered.

 

[droneuser]

the only thing about the panel antennas is you have to point them more towards the bird.....@mnoutdoors you need antenna tracking I post the link for that did you see it?

 

[mnoutdoors]

Keep in mind he is fly alot higher than us too, flying from a mountain.

I typically fly from 2100 elevation and end at 6000 in elevation. the top of the peaks I fly is 5900 feet
Normally I’m 300-400 ft AGL as I climb the mountain always straight line of sight

 

[mnoutdoors]

I don’t need a tracking antenna, I just move my body left or right, if I use my 20DBI antennas on the tripod I just give it a little turn remember as you get further away the antenna fan is wider on a panel antenna

ahhh ok I didn't think it fan that much

 

[mnoutdoors]

The narrowest beam I use is 18degrees, but some are 37 degrees at 10 miles 37 degrees is a lot of width

 

[mnoutdoors]

About 4 miles wide at 10 miles out roughly with 37 degrees beam
There are a wide variety of lobe designs and it’s not a true fan, it’s more of a lobe than a fan and as it gets further it does narrow. There are chapters and chapters on this and I’m not qualified to explain in detail

Just buy one of these

The dragon amp folks need to build a "20w" amp that's reasonably priced.

 

[mnoutdoors]

thanks for the info on the "fanning" of the signal and ya that 20watt amp not worth the price tag! but that brand name pricing is high on their amps!!

 

[droneuser]

@mnoutdoors you have any videos of your flying in the mountains? youtube? It would cool to see a video!

 

[mnoutdoors]

Only one

 

[Rnl]

If you go with a panel do you need two.
