the GAP is of most importance for impedance

strip width...? thickness...?
-
is a pcb antenna ? An all wire or metal sheet (NO DIELECTRICS) would ALWAYS be better...

ACIS .sat sab What year...? or STL iges step NASTRAN...?

TV dish with support 69 cms 69 cm tv dish.cst

use THIS one o change material to PEC or any metal offset dish.cst

nop...but maybe JOMY have one... diameter F/d ?
-
you could start with my model and tweak it to your needs...CST MWS 2020
-
well i personally ADAPTED 3,5 ghz and 5,8 ghz designs to 2.4 ghz ... any antenna could be UP-scaled or down-scaled... haven't tried slot feed yet...(it seems hard to get it right on DIY) but the PATTERN and PATCHES design could be used on ANY frequency system...(MiMo array) CP There's NOTHING unusual on the design...(except the electronics and the frequencies) feel free to delete

each CIRCULAR PATCH (director too) FLOAT on dielectric NO CONTACT... Energy is fed trough slots at 90 degrees from each IC Driver one for each circular patch Circular polarization , slot feed , direct IC drive...ACTIVE PHASED ARRAY (for satellite pointing)

analysis

Modified for COPPER TAPE over PES (styrofoam)
-
each floor (cement...?) would steal at least 3db...if you are right on the BLIND SPOT (on top of the antenna) you'll get almost zero...giving the antenna some angle and using a reflector (small flat aluminum , foil could do)concentrating the energy on your receiver from the built in antenna (it seems to be a 2 dbi or less)
-
best BOOSTER is a better antenna...(might require surgery...minor) if the stock is not detachable...
-
Starting point this site by Graham Sharples 13 cm bifilar helix I'd never found a good feed for DEEP DISHES ( i have a 1,26 m , 0.31 m deep dish F/d 0.25 )
-
what about supporting the actual set-up with a GIMBAL allowing the antenna and router (with slack in cable) to stay at 90 degrees to level (maybe adding some ballast in the base) under 5 dbi wouln't do it for 800 mts and obstacles (disc cone) not sure
-
Here's TWO things you might wanna try , BEFORE changing antenna,...(my 2 cents) The same 8/9 dbi UP side DOWN (diagram might point better to ground) lower angle A HAT (aluminum disc) on top of the same antenna (pushing energy down to AP) lower angle (BUT if 800meters 8/9 dbi (with lots of obstacles i assume) is NOT enough closer to 15dbi should do it) New antenna and finding the right HEIGHT you see...when the mast swings your AP falls OUTSIDE the LOBE of reception UP or DOWN...but OUTSIDE...
-
it seems like you gonna need a DUAL BAND omni (with high gain but wide angle of elevation or small angle pointing DOWN) What's the distance to AP...? (average)
-
the router model ... to check the use of two antennas...(separated a feet or so could be interesting) pretty sure is the ELEVATION ANGLE going UP and DOWN
