Endlich habe ich es geschafft: Das Wetter hat gestimmt, und ich hatte Zeit ;) - perfekt für einen Vergleich der beiden Antennen...
Die Teststrecke erstreckte sich vom Startpunkt bis zum Schafberggipfel, den ich anvisiert hatte. Zumindest war das der Plan. Beim ersten Flug mit den Originalantennen bemerkte ich, dass auf dem Gipfel immer noch ein ziemlich gutes Signal vorhanden war, also musste ich improvisieren. Ich flog also zum am weitesten sichtbaren Punkt, der Hütte auf dem Rotsteinpass. Als die Signalstärke dort immer noch gut war, aber der Akku langsam nachliess, kehrte ich um...
Beim zweiten Flug flog ich ohne Umweg zum Gipfel des Schafbergs direkt zur Rotsteinpass-Hütte. Das volle Potenzial der Antennen und der Brille habe ich noch nicht ausgeschöpft... Dafür habe ich nicht genug Teststrecke und Akku eingeplant. Insgesamt bin ich von der erreichten Distanz sehr positiv überrascht. Es verleiht einem ein gutes Gefühl beim Fliegen, zu wissen, wie viel wirklich möglich ist...

Finally, I made it: The weather was right, and I had time ;) - perfect for a comparison of the two antennas...
The test route extended from the starting point to the summit of Schafberg I had targeted. At least, that was the plan. During the first flight with the original antennas, I noticed that there was still a pretty good signal at the summit, so I had to improvise. I flew to the furthest visible point, the hut at Rotsteinpass. When the signal strength was still good there but the battery was running low, I turned back...
On the second flight, I flew directly to the Rotsteinpass hut without detouring to the summit of Schafberg. I haven't fully utilized the potential of the antennas and goggles yet... I didn't plan enough test route and battery. Overall, I am very positively surprised by the distance achieved. It gives you a good feeling when flying, knowing how much is really possible...

Thanks for the comprehension video . Yes , i also noticed that even the iflight patch antenna is better in over all performance than the stock ones.

Top Test und Video !! Klasse Darstellung 👏👏. Die Stock-Antennen sind mir demnach fast sympathischer und die Reichweite finde ich für dieses Antennensetup (keine Helicals) schon wirklich beeindruckend 👍.

@swissfpvshots 4 месяца назад

Danke. Ja ich bleibe jetzt auch bei den Stockantennen.

@jimross898 4 месяца назад

Directional patches are really hard to get aimed perfectly when on your head, particularly at distance. Would be interesting to see how they performed with an antenna tracker where you know you're aimed well. But regardless, surprising performance from the stock antennas for sure.

@PiotrMarkiewicz 3 месяца назад

I agree that stock antennas are surprising but I had same question about proper "tracking" but I'm afraid in mountains antenna tracker may not be best solution. Apart from that patches have circular polarization, was matching antenna installed on copter?

Danke, nein ich habe gedacht, dass die Patchantennen viel besser sind. Bei den Goggles V2 war es zumindest so. Da wurde ich eines besseren belehrt😂

@Michelsen3K 21 день назад

Das kann man so nicht pauschalisieren. Bei Patchantennen reicht manchmal eine kleine Abweichung die das Signal negativ beeinflussen. Da ich selber solche Entfernungen (mit Walksnail) fliege weiss ich wie das mit den TrueRC Patches ist. Eine kleine Bewegung nach links oder rechts und schon ist Signal/Bitrate besser. Nichtsdestotrotz, die Leistung der Standardantennen von DJI sind beachtlich. Ein Topergebnis!

@flipsfpv 4 месяца назад

Very interesting - thanks for sharing! With the Goggles V2 you definitely noticed a big difference with X-Air patch antennas. Especially from a distance of 3km. However, you always have to point the head or the antennas in the right direction, otherwise the connection is lost. This could partly explain the signal drops. But I agree with you: it's better to accept the barely noticeably "weaker signal" and not have any sudden, sharp drops of signal 👍

@swissfpvshots 4 месяца назад

I agree with you... I also had the V2 goggles and got week signal after 1km... but with patchantennas it got much better...

@YosepAliSaputra 4 месяца назад

very nice test dude🙏🏽 maybe you need to test ORT Helical in 3turn (for wider flight area) or 6turn (for less wide but more longer distance maybe)

@backinblack4492 4 месяца назад

Thank you for your interesting test. If I understand the graph correctly, there is no point in buying TrueRC antennas since they are no better than the original antennas with a signal that is even more unstable at times!

@swissfpvshots 4 месяца назад

hi, you could say that. It's obviously not a scientific test, and not super accurate, but in my opinion these patch antennas can't do much more than the original ones...

@squirrelynutz1 3 месяца назад

They perform much better. You need to stay within the 30° degree beam once a few km out. I've gone to 20km easily

@ra_Amon Месяц назад

Have you flown with the stock antennas (that have linear polarization) and an antenna with circular polarization on the drone (Momoda 5.8G RP-SMA LHCP 120MM) and have you reached the same distance as with a patch with circular polarization? What would happen if you set up the same type of polarization on both sides with stock antennas?

@BarryAllannussy 3 месяца назад

nice video comparison but I noticed the height is different between 2 video as video on the left fly much lower than on the right which higher you fly will get better reception but stock antenna was performed quite well lower height and it was getting better when you fly higher.

@etric4947 3 месяца назад

@SKILLFULfpv 2 месяца назад

Intéressant tout ça.😮 Vu que les antennes patch truerc sont plus directives, plus difficile de voler avec pour garder un signal en continu.

@FpvDevilbreath 3 месяца назад

To me seams strange. I did more o less the same test and in my case patch was much more than standard ants. Something very important is to have the ants streight to the drone. If you turn your head or you look down(or up) as many ppl doing FPV, so your result start having some sense...

@pixxair 4 месяца назад

Thanks for the test video. Were the TrueRC antennas LHCP or RHCP? What antennas were on the drone? I have LHCP antennas on my MOZ7 and the LHCP version of the TrueRC antennas on my goggles 2 and have much better range in my tests. If you have linear antennas on the drone and LHCP or RHCP antennas on the goggles, your range will be less by about 3dB.

This was what I was wondering, if linear on drone and co on goggles your not getting the advantage of either, I would actually like to see a test of linear on drone and linear patch on goggles, I've wondered if with digital in this type of environment do we really need cp and would it just be better having the extra gain, but then you have to be careful about were the bulls are pointing

looks questionable. It's clear that the quad was much higher in the flight with patches. That makes a huge difference.

Sehr schön animiert. Hast du das mit einem tool gemacht? War die orginalantenne am copter? Wenn ja, wäre die true rc im nachteil, da orginal ja neutral, u true rc lhc polarisiert wären.

Vielen Dank. Das habe ich mit einer Excel Tabelle erstellt, und in Davinci Resolve "animiert". Ich habe die Original-Antennen verwendet. Die sind aber, gleich wie die TrueRC Antennen, LHCP polarisiert... Zumindest laut GepRC Webseite

@@swissfpvshots oh, hab gehofft, dass es da was gibt was einem etwas arbeit abnimmt beim animieren. Aufwand lohnt sich aber bei dem ergebnis! Wenn ich nach der orginal antenne suche, findei ich diese als linear. Hab aber auch websites gefunden welche dual polarisation erwähnen. Ev macht geprc ja auch eine lhcp rein, wäre auch möglich.

bad test, things on the quad/setup is not optimal here). have done 23.5 km with these antennas! 28 mbps at 8,6 km, and 12 mbps at 23 km ( one way) i would reccomend these anyday over the stock antennas. use the 15cm antennas from true rc with the quad! and fcc hack on the goggles, also use channel 3 in manual mode for more stable signal( over wifi interferance)
