**(1) Value of Capacitor**

Try using lower value of capacitor, say 1.5 pF. If you dont have 1.5 pF, put 2 capacitors of 2.7 pf in series, and it will give you 2.7/2 = 1.35 pF

**(2) Distance from antenna at which Capacitor should be inserted.**

Try reducing & increaing the distance of splitter from antenna, 1 cm at a time.

Point of insertion along coax should be:

n x L + 0.85 x L,

where L = ½ wavelength in air (138 mm) x VF of coax,

and n can be any whole number 0, 1, 2, 3, ..., 10, .... etc, but n being smaller, the results are better.

So if n is selected to be 0, distance should be 0.85 x L, i.e. slightly less than ½ half wavelength.

The factor 0.85 above is rule of thumb, best value to be found by trial & error.

.....but decreased by 40% thanks to rainwater getting into the two-way splitter.
