The kit has been designed in order to have a medium power termination usable up to 2.5/3 GHz, it includes all the necessary parts for installation except the heatsink that is not provided.
Regarding the connection to the termination, the kit includes four types of coaxial cables so that the user can choose the solution that is most convenient, however, to achieve the best performance over 1.5 GHz it is recommended to use 141 semi-rigid and handyform oaxial cables.
We suggest to use a heatsink of at least 15 x 15 cm for a continuous usage, this dimension may be reduced if there is a forced ventilation or the usage is not continuous.
The installation is very simple and below there are a few tips to get the best result in frequency, in fact, the printed circuit board included in the kit has not only the purpose of electrically connect the cable with termination, but also acts as an impedance matching circuit, see the instructions below.
To solder the coaxial cable to the metal box you need to use a welder with a good power and a temperature of about 400 °C, it is better if the box is pre-heated with an air heater.
The 4 fixing screws of the termination and the printed circuit board are made of stainless steel so they behave like self-tapping screw into the aluminum box.
|TN-F9 termination return loss|
This graph shows the return loss obtained from two assembled kits, with a correct matching it is possible to reach good performance up to 3 GHz .The matching is obtained by using one of the included .141 semi-rigid or deformable coaxial cables.
