    first of all what frequency band you are using if 900 then in mode select F1=880 and F2=960 and follow the steps bellow or send me your E-mail and i’ll send you full document aboutanritsu site master .

    Step 1. Using the Up/Down Arrow key, select F1 (start frequency) and press ENTER. Enter the desired numerical value using the keypad or the Up/Down Arrow key. Press
    ENTER when data entry is complete.
    Step 2. Repeat the above for F2 (stop frequency).
    Step 3. Using the Up/Down Arrow key, select RES and press ENTER. Enter the
    desired numerical value using the keypad or the Up/Down Arrow key.
    Press ENTER when data entry is complete.

    when i calibrate with a original jumper i see vswr value 2.1
    then i calibrate with a rbs 2202 jumper(one of H1,H3,J1,J3) i see vswr value 1.24.
    which is true ?

    It almost Jumper problem because the values denote that.
    VSWR value accepted till 1.3 if greater than this it is bad value and as you said you get 1.24 when using rbs 2202 jumper.So try to replace the jumper and calibrate again.

    For bird sitemaster …im sure there is a diplexer somewhere in your feeder-line and while your 900mhz measurement is ongoing on one sector the same sector on 1800mhz is transmitting hence there is a loop-back of rf which is greater than the value the bird sitemaster in-built filter can take hence the issue with your sitemaster OPEN result display even when the load is on the jumper…

    Always power off the entire site if you want to do a complete feeder-line upto the antenna port using a load at the tower top.

    If you are just taking the measurement from the jumper without removing the jumper all the way to the top no need to power up all sector.

    Get an extra 50db load it would help in absorbing the excess coming off your transmitting module in a live environment.
