Test video for a DIY P3/Inspire booster. He runs out of range at 2500m using stock P3 antennas. Then he puts the DIY boosters on and goes to 4100m where signal is still strong but he has to turn back due to batteries. That's a 64% increase. Not bad for less than $2 worth of material. Some folks using P3's are reporting up to a 3X increase. AND it doesn't require any drilling, wiring and won't void your warranty.
Kinda makes me wonder about the value of the $100-$500 mods. The battery after all will be the limiting factor it appears in any range increase like this. If we can get a 63-3000% increase in range for $2-25, that seems like a much better cost/benefit ratio to me than the expensive mods.
• Material required: cardboard, aluminum foil (or aluminum/copper tape)
• Tools required: printer, scissors, utility knife, glue, double tape (I use double tape to stick aluminium foil onto cardboard)
• DIY steps:
1. Print 2 copies of the PDF template on A4/Letter size paper (or direct on cardboard if your printer support) from the download link: https://drive.google.com/file/d/0B6EvPgvmsFJlcVZ3QU5BZlFkVkk/view?usp=sharing
2. Follow the steps: https://rchelimenace.wordpress.com/how-to-build-your-own-windsurfer-antenna/

Personally I bought these 3D printed shapes I found on eBay and you just add reflective foil ($25).

Here's another guys design:
Note: I posted this info on Facebook and guys who do the mods and guys who have had it done were very quick to poo-poo the DIY solution, which is expected. One guy reportedly makes $60,000.00 USD/month doing antenna mods do he obviously has a vested interest
.
Anyway, for free/$25, I figured why not give it a try, so I am.
I'll post back here when I get a chance to test them.
