* Input, 50 ohms, SO239
* Output, 50 ohms, SO239

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 LISO Isolates the Coax or transmission line from the Radio to perform two functions....
1) Prevent any stray RF that may have ingressed into 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 parasitics that cause TV Interference are reduced.  Only a BALUN is to be used at the Antenna feedpoint.  DO NOT use a Line-Isolator at the antenna feed-point.

When vertical antennas are installed above radial system, the feed-point impedance is approximately 44 ohms. When they are
install without radials 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 on to the feedline.

To circumvent this problem with RF being induced into the shield of the coaxial feedline, we isolate the coaxial feedline from the RF currents from the antenna 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 where it adds to the gain/band-width factor (efficiency) of the vertical antenna.  The BUXCOMM LISO also reduces noise and other broadband signals picked up by the coaxial feedline.

IN short, the BUXCOMM LISO2K minimize radiation from the coax shield.  It further reduces TVI and RFI. RF in the shack.  For optium performance, insert the LISO in line with any coax fed antenna.  DO NOT install it at the antenna feed point.  Install the LISO at the output of the Linear, or at the input of the coax feed-line.  The BUXCOMM Line Isolator's primary design is to choke-off RF currents that can flow along the shield of the coaxial feed-line.  This can happen if you are using an unbalanced antenna system. 

The BUXCOMM LISO2K does not require any further tuning.  The LISO2K works great with Windoms, Dipoles, Bazookas, Sky-wires, and Loops. The BUXCOMM LISO2K is very broad-banded, and is useable from 1.5 to 70 mHz.
