i have a lot of modules aka slave devices that only have the basic non pa+ type card. then i have a master that uses the pa + card. The master can send messages to the salves from some distance but i cannot get the messages from the slaves after about 20 ft. I dont like the big antenna sticking out of my cases but would it make sense to use all pa+ cards at this point. im running 250kbs and max output. i was thinking about printing a case so i can just put the antenna and card in the case. Is there a stick on type antenna that i can peel the back off of and stick it to the case and still have the sma connector. or a tiny tiny antenna?
I have a pair on low-power nRF24s (with the PCB antenna) working outdoors with clear line of sight at 110m. And I have certainly had them working indoors at a range of 30ft or 40ft, including from a different room.
So if you are only getting a 20ft range with a high-power nRF24 at one end there is something strange. Are there obstacles between the Master and the Slaves? Have you tried working on a different channel?
You need to post your programs.

i can transmit 80+ ft away indoor when sending the message from the high powered nrfcard. I cant say the same about the low power card. the high powered card is not picking up messages more than 30 ft away from the low powered cards. i tried two different antennas. i have a stubby antenna and one that folds 90 degrees. the folding antenna got me 30 40ft of unreliable connection distance. the stubby antenna was only good for 20 ft. both cards have their own 3.3v regulators and filtering caps checking with a scope shows a pretty noise free power supply. what kind of antenna should i be using for best possible range indoors on an amplified card? i would hate to have to upgrade all these nrf cards to high powered ones.
Here is a link to the high powered one im currently using.
Here is a link to the low powered salve cards.
Here is a link to the high powered cards i bought tonight hoping for better results?
I tried different power supplies, different antennas, different nrf cards, shuting down all wireless devices/ the biggest difference seemed to be the antenna.. it slightly helped the high powered card receive messages from almost twice a far away. i wish i could find an antenna that just sticks to the lid like tape.
