The G4YKB Longwire is a longwire Antenna in name only, to be used with an ATU to enable fixed station operating with restricted space, or portable users access to all the HF bands and more. 
At only 66Feet in length being extremely compact it has been designed for the end user with limited space, it is reasonably covert with no T piece or traps to contend with therefore lends itself to installations in sensitive areas or where unsympathetic neighbours may be an issue. Ideally the wire element should be run in a straight line however where this is not possible it will function in a inverted V ,dog leg, inverted L or most other configurations to suit any particular situation and location.
In certain situations depending on height, configuration, ground type and surrounding obstacles you may find that an ATU is not needed on certain bands. 
The G4YKB Longwire is virtually plug and go, no tuning or trimming or adjusting is required, along with no requirement for a counterpoise or ground lead. It is of course essential that the station equipment has a good RF ground to allow the antenna to tune against earth. The G4KB Longwire comes complete with insulators,securing cord,full instructions and 2"/50mm pole clamp  plus enough self amalgamating tape to seal your coaxial connection
