For optimum operation, no adjustment is necessary. You can only make a fine adjustment on the 7Mhz band, slightly sliding its upper rod until you get the right resonance.
Remember that your Bazoka-Pro is a mobile broadband type antenna with small dimensions, so that the antenna propagation efficiency can be reduced to 1/10, due to its Broadband structure
The use of antenna coupler is recommended.
Be sure to use a large bracket, according to the size of this antenna, since your Bazoka-Pro is a heavy and large antenna.
Your Bazoka-Pro can be installed both in a vehicle, as on a metal balcony or other surfaces.
Before installing your Bazoka-Pro in the vehicle, make sure that the antenna is properly connected to the vehicle chassis to obtain a good mass.
We suggest experimenting, to get the best performance from your Bazoka-Pro. For this it is interesting to change the location of the antenna in your car and find the place where the SWR is lowest. Certainly, the location of the antenna in the car directly affects its performance, so we suggest you consider this recommendation and do not fix the antenna to the center of the roof of your vehicle. You should experience other angles and even if possible, use other types of brackets.
Always operate your Bazoka-Pro as a portable antenna, we suggest you try adding to your Bazoka-Pro 4 radials (or as many as possible) between 8 and 10 meters long each.Another optionis to connect theantenna mountagood groundingbymeans of a cableof6mm2section.Both solutions are very good for improving the signal rate.
