Kraken SDR Dipole Antenna -VHF

1

We have developed Quarter wavelength dipole from VHF freq 30 -88 MHz.
We are using mini-circuits Balun transformer inbetween both the elements.
We are keeping the radius as 150 cm.
The response is not good.
However if we use monopoles ( Quarter Wavelength) response is decent.

Is there any changes to be done in the Kraken software in terms of radius or any other parameters to be done when using dipoles instead of monopoles?
Please advise.

Replied to your email too. But my first thought would be the cables. Are the cables all exactly the same length?

Photos and a deeper description of the dipoles, array and setup would be useful.

Also double check that you have the dipoles oriented the same way, with the gnd element pointing downwards.

Nothing needs to be changed in the Kraken software, apart from the radius.
