Quality aside, stay clear it's illegal - not certified.
<< edit - just spotted your VA3 call - I guess Canada has similar rules >>
Capable of operating on CB frequencies and likely no band switched harmonic filtering.
"§ 97.317 Standards for certification of
external RF power amplifiers.
(a) To receive a grant of certification,
the amplifier must:
(1) Satisfy the spurious emission
standards of § 97.307 (d) or (e) of this
part, as applicable, when the amplifier
is operated at the lesser of 1.5 kW PEP
or its full output power and when the
amplifier is placed in the ‘‘standby’’ or
‘‘off’’ positions while connected to the
(2) Not be capable of amplifying the
input RF power (driving signal) by
more than 15 dB gain. Gain is defined
as the ratio of the input RF power to
the output RF power of the amplifier
where both power measurements are
expressed in peak envelope power or
(3) Exhibit no amplification (0 dB
gain) between 26 MHz and 28 MHz.
(b) Certification shall be denied
(1) The Commission determines the
amplifier can be used in services other
than the Amateur Radio Service, or
(2) The amplifier can be easily modified
to operate on frequencies between
26 MHz and 28 MHz."http://www.gpo.gov/fdsys/pkg/CFR-2011-title47-vol5/pdf/CFR-2011-title47-vol5-sec97-315.pdf
