Just wondering - should one take Rx sensitivity into account? -85dBm vs. -90dBm will make some kind of difference?

@cactus - now that's ambitious/creative thinking! I think I'll add it to the v2034 list though - a bit beyond my immediate abilities!

@Picofly - the calcs are based on the assumption of a -85 receiver. If you use a higher sensitivity receiver and only if the noise floor allows it then yes, you'll get better range

@papabatman - added the biquad to the list!

Quick update:
Added a few more power options (50, 250, 300 and 800)
Added the vulcan and biquad

Reordered the antennas alphabetically to make it easier to find them now that they've multiplied!

weird a duckie is better then a inverted v so when i mix cp and liners i can get better range. how accurate do you think this is?

I feel it's fairly accurate... if anything it reads slightly under if you can put up with some picture degradation.

Great work by the way Proto.

Hi guys - I've made a change and would like to hear your feedback...

Because the number of antennas is getting quite large I've added "sections" to the lists. In both Tx and Rx antennas you now have a group for "control" and a group for "video" and within that the antennas are sorted alphabetically. Is this useful or not and are all the antennas where you'd expect them to be?

Thanks!

Hi guys,

Soooo by popular demand I'd like to introduce the maxmyrange advanced mode. Just select it from the front page, enter all your details and "lets fly".

Do let me know what you think and any improvements you'd like!

3.9 miles errrrrr no. Lol my rssi indicator begins getting low at 500 meters at 200 feet high with picture almost fully lost. Bit wrong for me im affraid :-(

900mhz 100mw with clovers

Hi theroots.

I checked again and also against disco tuna's spreadsheet and indeed that is your theoretical max range. Perhaps its worth checking what else is affecting your setup.

Actually, seeing as you're based in the UK 900 may be an unlucky choice as it seems it is used by mobile phones. If thats the case your noise floor is through the room and you're lucky you even get 500m!

Well i run it at 1040mhz with no interference issues.

I guess il try some better testing and see what i get :-p

12.46 miles / 1.3 with Vee and 8dbi Patch.

Now if I could just get the nerve to go half that far!

Hi guys,

So, a month in and 37594 clicks later we have the latest leaderboard for maxmyrange, enjoy!

1) The most popular (as in, most frequently selected) frequency is 1.3GHz (41% of choices), then 5.8GHz (29%), then 2.4 (9%)

2) The most popular Tx wattage is 500-600mw (38%, not much of a surprise here), followed by 200mw and 1000mw. Anything under 200mw barely got a click while a good 9% chose 1.5W (“I know I shouldn’t really, but … what if…”).

3) Cloverleaf is by far the most popular Rx antenna (27%), followed by inverted V (15%), Rubber duck (12%), and skew planar (9%).

4) In terms of Tx antenna, with a much larger choice, selections were more spread out. Pepperbox and Yagi got 9% and 7% (people dreaming of those 50km flights?) followed by crosshair and cloverleaf (6.6%). The rest each got a few percentage points.

5) In terms of the all round highest scoring combos, for video we have the pair of cloverleafs on 5.8GHz and 600mw of power and for control, moxon/turnstyle on UHF 1W
