RC phase-shifter question- please help

[confi999]

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

**broken link removed**

( 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!

yes, you may be try it !

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
