Cat#  B2KLISO

160 TO 2 METER (1.5 to 175 MHz) LINE ISOLATOR and
EASILY HANDLES 3000 watts average power or 4000 watts
SSB.  The BUXCOMM B2KLISOtm is an ultra-broad-band
transmission-line-transformer (TLT) BUXCOMM exclusive.
RG8X Coax Jumper Cable with PL259 on each end is included.

We included, enough ferrite cores in the B2KLISO for effective
choking impedance. Our Line Isolation B2KLISO TLT is
conservatively rated
. It can easily handle 3000 watts RMS, 1.5
to 55 MHz HF, and 2000 watts at VHF.
The ferrite material we
use for the cores are made to our precise, wide band standards
to provide optimum performance across the Amateur bands
1.5 through 175 MHz,
No other line-isolator, UNUN, or BALUN
provides this level of isolation at these frequencies
, and power
levels.

BUXCOMM  B2KLISO coaxial in-Line isolator (B2KLISO) tm 
is isolated by multiple, ferrite cores transformer. 1.5 to 175 Mhz. 
Made with Multi-Mix Ferrite cores for wide bandwidth, and
Ultra-low-loss (0.5dB @ 10 mHz) coax.
See illustration and recommended application, this page:

The feed-point BALUN or antenna UNUN may not balance the
currents in the coax section feeding the antenna.  However, lower
down the coax line, near the RF output, a BUXCOMM
B2KLISO line isolator is added to reduce the common-mode current
on the coax shield, thus reducing the radiation from the feedline between
the isolator and equipment in the Ham Shack..

* Output, connector, SO239

B2KLISO
An Isolator is installed at the output of the Radio, and/or if you are using a Linear Amplifier, 
it should be placed at the output of the amplifier.

A Line Isolator is exactly what it says: ..... The B2KLISO Isolates the Coax or transmission line
from the Radio to perform two functions;
1) Prevent stray RF that may ingress onto the coax shield
from the nearby antenna radiation, And
2) Reduce spurious re-radiation or secondary radiation
that may be a product of the random length of the transmission line.
As a result of number 2), many parasitic's that cause TV Interference are reduced. 
Only a BALUN is to be used at the Antenna feedpoint.
When vertical antennas are installed above radial system, the feed-point impedance is
approximately 44 ohms.  When they are installed without radials or a counterpoise, there
are losses that enter into our equation that defeat the gain/band-width factor of our
vertical antenna(s).  In addition, the feed-point impedance is no longer (approximately)
44 ohms.  Some reduced VSWR may be noticed, however, the gain of the antenna suffers
as a result of the antenna efficiency loss. There is a reason for this effeciency loss;
because too often there is (RF) current introduced onto the feedline shield.
To circumvent this problem with RF being induced into the shield of the coaxial feedline, we
isolate the coaxial feedline RF currents from antenna re-radiation, by inserting a
"Line ISOlator" at the base or feed-point of the vertical antenna.
The BUXCOMM LISO (line isolator) inhibits undesired RFI by preventing feedline currents
and re-radiation. In turn, the LISO forces all the RF energy from the transceiver, tuner, or
amplifier, into the antenna. 
The BUXCOMM B2KLISO does not require any further tuning. 
The LISO2K works great with Windoms,  Dipoles, Bazookas, Verticals and Loops.

*Style and color may vary.    Performance per above specs.

Important Note:
We recommend using CoaxSeal, CS104 on all BALUN terminals and
attachments.
Any BALUN installed out-of-doors is subject to harsh
weather, hard driving rain, and heavy winds. These conditions can allow
moisture to develop inside a BALUN when the connections are not sealed.
