Same here.I am running the DBS antenna by itself and am really impressed with it!
My buddy has stock antenna setup (for now) and we made some comparisons.
I can pretty much take my i1 right down to the deck anywhere within a mile on relatively flat ground and have full signal while the stock setup would lose signal under 100 feet.
I could fly behind buildings with some signal loss and the stock setup would lose signal completely almost instantly after line of sight was lost.
The difference is quite amazing over the stock setup and for $109 is some of the best money I have spent on this hobby in a long time!
I had both tx's modded
Had a slight issue that DBS handled awesomely
This upgrade makes my 2nd tx work, which didn't since the fw upgrade that took channels from us.
I get awesome signal, i1 can be facing any direction at almost any LOS range and signal is strong and latency seems minimal.
I am very happy with the whole process.
I modded the factory case to hold the antennas as well, disconnected.
