Try EMCO for horns and MITEQ for preamps.

Subject: Horn antennas, pre-amplifier, and return loss measurement
Hi, Folks,
Is there anyone can direct me to some sources
of horn antennas & preamplifiers.
What I need are sets of horn antenna for spurious
emissions testing to meet FCC Part 101.
1 to 18GHz,
18 to 26.5GHz, 26.5 to 40GHz, or 18 to 40GHz instead,
40 to 60GHz, 50 to 75GHz, or 40 to 75GHz instead,
75 to 110GHz, 110 to 170GHz, or 75 to 170GHz instead.
Due to the significant space loss over 110GHz, I guess
I also need a set of preamplifier from 110 to 170GHz.
I am also studying on return loss measurement
methodologies to meet ETSI requirement for
radios RF port. Since NAMAS calibration of
network analyzer may cost thousands bucks,
I am wondering if I could achieve a good result
(in terms of accuracy and uncertainty) using
spectrum analyser and waveguide coupler.
If anyone by any chance has an ready error model
of the test setup using spectrum analyzer and
waveguide coupler, I appreciate you could share
with me to short my research path.
Thanks in advance.
