Stacking your broadcast antenna will make your antenna have more gain. If your antenna have more gain, more ERP (Emmittion Radiating Power).
What do you need for stacking antenna?
- More antennas that identical each others.
- Power divider to distribute your RF power to each antenna.
- Jumper cables to connect antennas
Stacking for 4 Antennas
Antenna :
Prepare 4 identical antenna. Tune the antenna for Matching on the working frequency.
Power Divider :
Prepare 1 power divider with 1 port input and 4 ports output.
Jumper Cables :
any length of coax cable with 2 N connectors to connect between power divider and antennas.
Determine Range between Antennas
When you install the antennas in collinear system, you must observe the distant “D” (see drawing of follow page) between two antennas.
The formula for calculate “D” is :
D = 0.75 x λ
Where :
0.75 = is the multiplicative coefficient;
300
λ = -----------
F(MHz)
SWR reading on the frequency 94.4 Mhz <1.25
