"The antenna is a 7 db patch from Range Video and with the Frysky system without a booster they are getting around 4 kilometers range with it.

"Philip,
That is interesting about the attenuators as I put a 6db on my dx6 and the green light stays on. It would be nice not to have to add the attenuators."

"Thanks Sqt. Ric. Yes that would have been helpful to have a link on the page where I bought it like the SMD - U.FL adaptor. That would have saved me some time trying to figure out what was wrong :)

Skyler Guest, my green light on the booster now…"

"Well, the problem is solved and I don't know where to leave this information as the Drone store does not seem to have a customer service link. I bought both amps from Drone (500 mw and 1 watt) and both of the cables included are a male to female…"

"Is there a way to check the amp? or is the LED the amp checker :)"

"well the plug in supply they came with says input of .35a but output 6v 2000mh so that's two amps. I thought that was the issue but I just plugged in power from the one on my Speckrum which is rated at 5 amps but no luck. Would powering it up with…"

"hmmm - my ParkBEC is rate for continues 1.25 amps 1.5a 60 second burst. I don't know about watts sorry.

I just did a range check with the power down settings on the futaba and the antenuator removed and got 40 paces.

Interesting thought about the…"

"I have tried that several times - I have even tried a spare battery so I could have two different power sources.

Thanks for commenting and trying to help. I am at a loss..."

"after reading the info about the 1 watt booster from drone - I am starting to wonder if even with the 6db attenuator if the futaba 7c puts out to much for the booster? The manual for the booster states no more than 15dbm. Maybe that is why I got the…"

"I just got a chance to look at the same cable on another installation and it is the same way so it must be ok. I was at a friends house doing the installation and it did not make sense to me. Also, since there is no data I can find on which end to…"

"So I would think the connector would need a male pin on both ends or there is no center connection from the booster to the radio?"

"My antenna screws into the booster - the SMF cable that connects from the bottom of the booster to the radio - I would think that both ends needs a main pin. Does your connector have a male pin on only one side? Thanks for the help. I am at a…"

"I just received a new Booster for my Futaba 7c and noticed that the small SMF connector on has a male pin on one end. Should there not be a male pin on booth ends?"
