DJI FPV Antenna Test improved! (GPS + SRT = good comparison of Lollipop vs Patches)

Here's my take on practical antenna-testing for DJI FPV goggles. A lot of DJI users ask me, "which antenna should I use for decent range?".

Stock DJI Antennas (in the air and on your goggles) are ok, but with the cheapest of options you can gain way better results. I swap the air units antennas for RHCP so I can use all my normal 5.8 antennas that I collected over the years. (DJI antennas are not really different from what we used in the analog world). On the AirUnit you need: mmcx RHCP antennas (if RHCP is what you use on goggles). I use either Speedybee or Foxeer Lollipop mmcx antennas. Caddx Vista: attention - here you need "UFL" connector instead of mmcx! Foxeer Lollipop stubbies would be very convenient, but my previous measurements indicate that they are especially weak "overhead" (in the antenna null). Normal Lollipop (the ones with coax cable) are relativly small and have good performance. 2 of them cost around 20$ currently on banggood - so for 40$ you can have the goggles fitted with new antennas, if you dont already have these from analog times... Watch out - you also need RP SMA to SMA adaptors! Longrange combo: 2 omnis (the said Lollipop) on top (yes, on top - they look like horns there as well) 2 patches on the bottom ports (if possible use an 45° adaptor to point them straight or even up a bit!) In this video you see how much of a difference you can expect between already tuned Lollis and the Patch combo. Since I now have GPS RTH safety, I can almost go to the edge of my reception. With the SG325 iNav copter here I have the luxury of an SD card for blackbox logging - and therefore I get good GPS data (check Pawels tutorial on how to convert blackbox logs to GPX files for google earth: https://www.youtube.com/watch?v=GEGywqPD2Uk). And with my little script (https://youtu.be/s0Y-P3RrMDI ) I can convert the subtitles (SRT) from the goggles to Excel files and make nice charts which show you the bitrate over time rather then just the number overlay. That makes it much easier to judge the performance over the whole flight. SRT to CSV converter script: https://bit.ly/2Zr9Gs6 Test setup: 25mw, current firmware (as of 16.9.2020) 50mbit mode, high quality SpeedyBee Antenna on Caddx Vista Crossfire for control link Standing next to a road free LOS to the fiel, nothing blocks my view to the copter. "fly as long as you feel comfortable" - I returned when bitrate dropped below 5mbit too often. Summer, low humidity, 28° all flights around 5min from each other.

How this simple Adapter2 saved the day (SG325 + iNav RTH settings)

While waiting for the Flywoo Explorer LR I converted my Skystars SG325 to have Crossfire and Caddx Vista. So now I can test DJI goggles' antennas without freaking out all the time and I can go to the limits now for you guys ;)

Ride and Fly (KTM Adventure 390 and EMax HawkPro)

Continuing to edit the many joyful flights of my compact DJI FPV setup together. Here I started combining 2 great hobbies: motorcycles (newbie!) and Drone flying. This adds up to a degree of freedom I hope to somehow transfer into this video. You drive around in nice landscape, can go almost anywhere (with a decent adventure-bike) and fly if you arrive at a new spot. Sometimes hard to decided tho: do I rather keep going with the bike, or change to the drone ;)

Found this on banggood and requested it for review. Really nice package with the Caddx Vista already installed, I only had to switch the RX (the Crossfire version was out of stock). Already had a lot of flights with it - so expect LOADS of fun in this review! Please 👍 and 🔔 thanks ;-) it helps a lot! Find many links and infos further down! ►GepRC Rocket Lite (code:drones6, 6%OFF) + FUN little drone + loads of range + durable + easy to fly - flighttimes on 2" not so long (3-5mins) - a bit expensive (partly because Caddx Vista included) - noisy definitly should be flown with good 4cell packs: Tattu R-Line battery

EMax in the Woods (DJI DVR commented)

These were the first flights with DalProp folding props. Pretty windy, re-discovered spot (were there years ago with the little IRC Vortex150). Still catching up with using footage - I think the next of these videos will finally come with 50mbit DVR and clearer video. Still totally happy with the emax which has become my fav quad this summer! 

INSIDE DJI Caddx Vista and other micro antennas (Lollipop, Speedybee)

Today I wondered how the Caddx Vista antennas look inside. Couldn't find the info online, so I opend one up myself. Before I knew what happend, a lot of poor little antennas were mangled brutally and I needed to find an excuse for the slaughtery. "That's for a video" I tried to convince myself...

3 new spots: asked for permission, here's what happend!

This is the 3rd video in my "DVR Chronicles" series. I really fly a lot with DJI FPV (fun again) and the little EmaxPro (fast, light, small, long flighttimes).

Here I still have 25mbit footage (flew this a while ago). Now with 50mbit it looks even better and let's me keep the gopro safe (at home) - and makes the whole flying process so quick and easy! Thanks for being here - means a lot! Greets, Mario

Hope this helps you decide which antenna to use and what to expect!

►Antenna OVERVIEW (with pics & links)

►Detailed measurement data

My test-setup:

I use 1mW on the transmitter, 10m distance to a VERY SENSITIVE receiver (Aaronia Spectran HF6065 -150dB! and take enough samples to get an average. 

I measure antennas in their best orientation (vertical for omnis) and the worst (antenna null point "above" the omni antenna).

Fun fact:

As my test suggests that Lollipop 1 is better than 2 and 3, here I read that Lolli1 was PCB style (like Lumenier AXII) and 2 was spw style. That explains why the Lolli1 was their best antenna - because they cloned a good one :)

CADDX Loris "4k60", Ratel, Nebula analog Latency, Image quality and a BUZZARD!

If you're here for the Buzzard, check 11:46 ;) - in my Caddx Cam-Review I didnt compare the digital image vs. stock DJI, because we already know it doesnt look good. I measured the analog latency and give you an idea of the 4k60 quality you can expect from the 10gr Loris board cam.

DJIFPV Summer Riverruns (scary as s.... to fly that close and fast over water)

Found the confidence to fly more over our river "Schwarza" (Black river) on 5 different spots around here. Of course you need to powerloop that bridges - but throttle response should be trained to catch the copter before it's his last DIVE ;)
Hope this helps you cool down if it's hot, and hope it brings light, sunshine and warmth to you if you are down there in the winter!
