Can I use this simple RC phase shifter for HF frequency band:

https://www.music.indiana.edu/som/audio/Academic/A112/RCPhase-Shifter_files/frame.htm

( 1) Is it possible to simply put such phase shifter between antenna, tuner and transceiver and get the proper phasing?

( 2 ) To make it work in different frequencies is difficult as Xc will change. How can I modify it to work in multi-band?

Any suggestion, reference will be highly appreciated. Thanks!

i think you should go for a compramise between the two...if u are moving for multiband system means u can't keep ur phase shift as a constant.....
PHASE CONSTANT,θ=inv.(tan (1/wCR)))
FREQUENCY IS INVERSELY PROPORTIONAL TO R and C
