5 mast array [107.6mts] 1/4 wave is 115.75mts
these masts were intentionally shorter to prevent harmonics into co-sited 1296kHz/231mts
In the absence of RF phasing at Orfordness since Babcock stripped the transmitter hall, the antenna pattern remains almost omni-directional with a Bow-Tie @ 312deg. Nw ( >( O )< ) towards 132 s\E
Existing 4+1/4" feeder from transmitter hall was
only efficient at fraction of +500kW out to ATH3
If the Nautel2.5 is reportedly running at 2.2kW?
an estimated 1.8kW e.m.r.p. (effective monopole radiated power) and not the same as ERP for vhf
