How do i change the antenna type in this matlab code?

I am trying to change the antenna type used in this code. I tried to debug but i am not able to understand what syntax i must use to repalce the isotropic antenna with another. I am posting the code:

clear; clc;

viewer = siteviewer("Buildings","UoS.osm");

Latitudes = [51.2436, 51.2360];

Longitudes = [-0.6160, -0.6056];

BaseStation = txsite("Name","BS",...

"Latitude", Latitudes, ...

"Longitude",Longitudes, ...

"AntennaHeight",10, ...

"TransmitterPower",30, ...

"TransmitterFrequency",3.5e9);

show(BaseStation);

pm = propagationModel("raytracing","MaxNumReflections",10);

coverage(BaseStation,pm, "SignalStrengths",-120:-5, ...

"MaxRange",200);

Hi Josyula,

I understand that you are trying to change the Antenna type from isotropic.

You have used ‘txsite’ to create radio frequency transmitter site. If you don’t specify antenna in the ‘txsite’ function, the default is isotropic antenna. You can check this by running the following script

BaseStation.Antenna

To change the type of Antennas to dipole, the following script can be used

Latitudes = [51.2436, 51.2360];

Longitudes = [-0.6160, -0.6056];

BaseStation = txsite("Name","BS",...

"Antenna",dipole,...

"Latitude", Latitudes, ...

"Longitude",Longitudes, ...

"AntennaHeight",10, ...

"TransmitterPower",30, ...

"TransmitterFrequency",3.5e9);

For more information, refer to the doc

Hope this solves your query.

Thankyou for suggesting but I have already tried that. If i change the antenna type to dipole i get the following errors.
