Request:
700mw setting or a setting that lets you type in any number you want.
-because of 2.4ghz 700mw Immersion RC vtx and I want to see what a 10 gigawatt video transmitter will get me for range for when I build that hydrogen atomic thermal nuclear airplane I've always wanted.

are panel antennas any good? Maybe guess the range on some panels too.

Just for fun I wanted to say my real life figures are not too far off from your calculator
immersion 600mw 5.8
cloverleaf x2 = 1.87 miles
cloverleaf vtx and crosshair reciever 3.12 miles

Hey Parajared - so 10GW Tx eh? You can also fry an omelette while you're at it

Good news is that maxmyrange fully supports hudrogen atomic thermal nuclear planes!

All you need to do to try out all kinds of crazy combos is click on the advanced link which takes you to an interface where you can enter any values you like. http://www.maxmyrange.com/advanced.html

Regarding panel antennas - happy to add - do you have any links to specific antennas that are applicable to FPV?

I have specifically been interested in L-com's offerings but I can't find any rcgroups reviews of how well they work for FPV, so I guess I will be the test dummy when mine arrive.

2.4 mini panel

5.8 panel

They have specs under the "specs" tab or hidden away under the "downloads" tab and then click specifications

I entered some numbers for a 600mw 5.8 tx with standard blue beam 1.25 antenna gain and a 18.5 db rx like a Vulcan antenna and it gave me this. Does this even seem close to correct?

Freq is in MHz, so try entering 5,800 instead of 5.8.

Yeah I did that and forgot to correct it in my post but that still seems quite a ways. I wonder how high up I would need to go to get close to the suggested 8+ miles?

Hi guys,

Quick update on maxmyrange. Always trying to keep maxmyrange up to date I've added some of the trendier new antennas out here - shout if I've missed any. You can now select them from the dropdowns and also see their photos in the assumptions page (http://www.maxmyrange.com/assumptions.html)

Air-Blade
Airscrew
Super Cannon
DuraSpec
Race Spec Airblade
Race Spec airscrew
Triumph Antenna

Check them out at http://maxmyrange.com

Cheers,
Proto

Hey guys,

Alex here (from MaxMyRange http://maxmyrange.com and The beginner’s guide to FPV (http://guidetofpv.com).

Thought I’d share some interesting stats with the group for open discussion…

Over the last couple of years maxmyrange has had 20000 people run over 100,000 calculations. So all this activity produces some interesting stats about what gear people use (or would like to use!). Here’s some analysis of the data as well as charts of the main parameters for whoever’s interested.

- As expected 5.8GHz is the most popular frequency (53%), followed by 1.3 (19%) and then 2.4 (12%). The newcomer 3.4 was only added recently so not much activity (yet)

- In terms of power 600mw and 200mw were the clear winners (each with close to 20%). Interestingly extremely low (sub 50mw) setups got 13% of the attention – this is especially interesting as the same stat two years ago was close to zero – legislation impact perhaps? Finally, extremely high (over 1000mw) also got a lot of attention (19%) – “I know I shouldn’t but… what if…”

- When it comes to antennas by far the most popular combo was pair of cloverleafs, with 12% of all calcs, with a good proportion of them running 5.8GHz at 600mw

- The video Tx antenna lineup was cloverleaf (49%), mad mushroom and skew planar (12%) followed by the rest. Interestingly the same stat two years ago brought rubber duckies close to the top – I guess people are becoming more sophisticated and/or better informed

- The Video Rx lineup was cloverleaf again (16%) and then a mix of long and short range options at 5% (16.5db yagi, skew planar, pepperbox, mad mushroom)

- In terms of UHF control Tx we had the standard diamond (32%), yagi (18%) and then 1/2wave dipole and moxon at 17%

- Finally the selection of UHF control Rx is quite limited with 76% of calcs going to the 1/2wave dipole

Now, I’m not at all sure what this really means – does it show us what setups people use? Or maybe what they’d like to? Or maybe that people just like playing around!

Any grand theory on what actual useful conclusions can be drawn from this?

-That people are selecting "inverted V" for control rx because there is no option for a rubber ducky (monopole) rx?
-that far too many people are using cloverleaf antennas to receive 5.8 video?
-that some newbs are running 2500mw to boost the range of their crappy antennas?
-that maxmyrange hates ground vehicles and there are no full wave rx/tx options?

Woa! Totally uncalled for! I can positively testify that maxmyrange ADORES all kinds of FPV vehicles. Glue a camera and a VTx on a stick and MMR couldn't be happier.

Actually, I'll take the opportunity (as if I needed an excuse) to prove the point by shamelessly parading my gimballed, rollcaged, FPV'ed Summit that I'm totally bananas about.

FPV Traxxas Summit build - 3 axis gimbal and custom rollcage (6 min 55 sec)


Seriously though - if you think there's something ground vehicle related that's missing let me know and I'll add it right away.

Sorry, what I meant that "maxmyrange hates ground vehicles" [sardonic inflection emphasized]. I read somewhere about people sticking big ol' 5/8 and even full wave LP antennas on their ground vehicles (like 5 feet tall!), but I have never heard of anyone doing this on a plane. Have you tried this on yours?

Ha, that's be a sight. No I haven't. I've compared LP vs CP for the areas I drive in and CP was better. I'd love to try out some full wave LPs - any idea where to get hold of one?

Hey guys, wanted to let you know I've added a bunch of relatively new antennas to http://maxmyrange.com (Lumenier, Axii, TBS Triumph, TrueRC Singularity, X-Air and X2-Air).

FYI, you can see the full list of 36 antennas, their photo and specification here: http://www.maxmyrange.com/assumptions.html

And, finally, a request - if you can think of any FPV antenna that's missing please shout! Lets make this the most comprehensive list of antennas on the web
