I get questions every day regarding the
P4P antenna and currently over 300 people signed up to be notified when it's available. I'll admit, 5.8ghz works great for me too and I don't need the upgraded antenna, but other people do. It just all depends on what type of interference you're flying in. I've heard from plenty of people who say 2.4ghz works better for them and that both suck from others.
I strongly suspect this is a training issue. Not everyone is a veteran with our experience.

I never considered using Auto 5.8 GHz, and was getting terrible range using 2.4 GHz with the 32 Channel Hack set on manual on Channels 30-33, which are what I have used successfully out to 6 miles with my P4 with the boosted DBS-02 antenna over the last year in the same area. My stock
P4P results on 2.4Ghz were consistent with my terrible stock P4 results, so I gave up, and waited for a new
P4P range extender. Then, some random new guy on the forum claimed he was getting over 4 miles stock on the
P4P. I challenged his "outrageous" claims, and eventually got him to share his settings to see if I could replicate his range using those same settings. Low and behold, he was right, and made a believer out of me. I initially thought it might be a fluke on a few aircraft. However, the same setup works on all six different
P4P aircraft I have owned!
First try Auto 5.8Ghz with a $15 windsurfer. If that doesn't work, then consider a range booster, but a range booster will likely only replicate the Auto 5.8Ghz range on the 2.4Ghz band, and supposedly the 32 Channel hack has been disabled on newer firmware, but still works on mine. All my results are based upon clear LOS. If you can't get good Auto 5.8Ghz results, with a windsurfer, with the
P4P, you likely have LOS issues that even a range extender won't help with. Get up higher, and out from behind any LOS obstructions for the best range. YMMV.
