SS-11 The SS-11 Field Strength Meter is ideal for reading relative field strength from your antenna. It is a compact unit that fits in the palm of your hand and can be taken anywhere. The best part of using it is that you now can tell if your antenna is radiating or not by simply holding the unit near your antenna and adjusting the sensitivity. Also, by taking measurements, you can find out relatively how strong your antenna field is. Operation The SS-11 Field Strength Meter is very simple to use. It requires no power because your antenna field provides the power necessary to run the meter. Simply raise the single whip antenna on your unit, stand several feet away, and adjust the sensitivity knob on the front, it’s that easy. You want to ensure that the whip antenna is parallel with the polarity of the antenna you are reading. Now you can read the relative field strength of your antenna.

Technical Assistance If you have any problem with this unit first check the appropriate section of this manual. If the manual does not reference your problem or your problem is not solved by reading the manual you may call SURECOM Technical Service at 852-54457217. You will be best helped if you have your unit, manual and all information on your station handy so you can answer any questions the technicians may ask. You can also send questions by mail to SURECOM.COM.HK Features: The appearance is simple and efficient, beautiful and generous.

Small size, easy to carry, size: 75 x 100 x 64mm (excluding the raised antenna part) Instructions for use: Before use, please rotate the "amplitude adjustment" to the left most end. The length of the antenna to be pulled depends on the frequency of the test. It is better to have 1/4 wave as much as possible. The handheld walkie-talkie is about one meter away from the field strength meter. Don't be too close! In order to avoid the signal is too strong to burn the field strength meter! Then press the walkie-talkie PTT button to make the walkie-talkie enter the launch state. At this time, the pointer of the field strength meter should have a signal indication. The stronger the signal, the greater the indication! Amplitude adjustment: If the field strength indicator indicates that the maximum range is exceeded, the "amplitude adjustment" can be adjusted to let the pointer indicate the appropriate position. Method for testing the maximum gain point of an antenna 1. In order to change the frequency conveniently and quickly, you should use the keyboard to set the frequency walkie-talkie manually. 2. Link the walkie-talkie and antenna feeders, place the field strength meter near the antenna (depending on the environment), place it within the vertical radiation angle of the antenna as much as possible, and the antenna planning method is best. 3. Set the frequency of the walkie-talkie, press the launch button, observe the meter reading, and register the meter reading. Then set the walkie-talkie to other frequency points, let the walkie-talkie enter the launch state again, observe the meter reading and then compare the readings of each frequency point! You can know the best frequency/segment of the antenna under test! A typical field-strength meter is shown in Figure 1. This is a simple passive (unpowered) circuit in which radio frequency energy is intercepted by the antenna, rectified to DC, and then used to directly drive the meter. The maximum sensitivity of this circuit is based primarily on several factors: The gain of the antenna: How much of the signal is actually intercepted. The sensitivity of the meter movement being used. The nature of the diodes being used. If you have related videos, please share with us, please contact us

Q1)

Q1) Very high calibrate and not accurate when I transmitte to my UHF radio base to SW-111 A1) The frequency of SW-111 is 27MHz, it not for VHF UHF radio Q2) Can I plug in a SMA cable on SW-111? A2) the Antenna & TRANS connector of SW-111 is SO239, if you want to connect with a SMA cable, you need to add an adaptor Q3) Hi SW-114 can detect SWR and watt without cable? A3) No, without cable, you can only measure the electric field strength. If you want to measure SWR, you must have a cable. Q4) The Surecom 111 power meter needs more instructions. What do each of the numbers on the screen mean? I need to know if my power is 5, 10, 20, 30, 40, 50, 60 watts? A4) The numbers 0, 1, 2, 4, 6, 8, and 10 on the display are for checking 10W of power. If you want to check 100W of power, simply multiply the numbers by 10. For example, 1=10, 2=20, 4=40 Q5) Do I need to buy a jumper cable for SW111 / SW114? A5) SW-111 / SW-114 do not include any connecting cable, therefore you need to buy it Q6) Can this be permanently left attached to the CB cable without affecting the signal? A6) We don't suggest for long-term connection, because long-term connection may cause deviations in SWR or power readings, especially under high power or high frequency environments. Regular calibration or temporary removal of the test is recommended.
