help with coverage antenna toolbox - eNB (LTE base station)

Hello,

I'd like to edit the code below to add things that are true for an LTE Base Station (eNodeB), like free space path loss (instead of close-in), add antenna down tilt (of 4 degrees), and any other relevant changes. the only thing I can get to run is the example code of coverage() shown below, if I add any changes it erros out.

%% Transmitter Array % Specify the names, latitudes, and longitudes of three transmitter % locations.

names = ["Site381254","Site381077","Site383046"]; lats = [40.083915, 40.063641, 40.086335]; lons = [-105.169347, -105.076260, -104.984694];

%% % Define the frequency of the transmitters.

fq = 2145;

% Create and view the transmitter array. 62 dBm

txs = txsite('Name', names,... 'Latitude',lats,... 'Longitude',lons, ... 'TransmitterFrequency',fq, ... 'TransmitterPower',62);

show(txs)

%% Powers coverage(txs,'close-in','SignalStrengths',-40:5:-10)
