INSTALLATION INSTRUCTIONSHUSTLER 4-BTV,5-BTV TRAP VERTICALWARNINGINSTALLATION OF THIS PRODUCT NEAR POWER LINES IS DANGEROUSFOR YOUR SAFETY,FOLLOW THE INSTALLATION DIRECTIONSGENERAL DESCRIPTION:The Hustler 4-BTV is a four-band trap vertical antenna providing an omni directional pattern.The 4-BTV is designed as a self-supporting vertical to provide optimum operation in the 10,15,20 and 40meter bands.It can also be adapted to operate in the 75 meter band.This antenna is designed forinstallations with restricted space.The Hustler's 5-BTV is a five band trap vertical antenna adding 75/80 meter operation to the 4-BTV.This is achieved by adding the RM-80S resonator and 4457-1 spider assembly (see diagram page 3).The Hustler 4-BTV provides electrical selection of bands through the use of optimum Q traps,which areindividually and precisely tuned and internally sealed at the factory.Tampering with the traps willrender your warranty null and void.The traps are parallel tuned circuits which provide efficient isolationbetween the vertical sections,permitting multi-band operation.Broadband operation over the entire hamband at very low SWRs is possible in a proper installation.Operation in the 75/80 meter band isprovided by installing the appropriate resonator on top of the 4-BTV.The Hustler 4-BTV was designed to provide optimum performance from both an electrical andmechanical standpoint.Mechanically,this antenna boasts a heavy duty base and heavy duty aluminumtubing.The mechanical assembly is accomplished with all stainless steel hardware.The use of clampspermits readjustment if necessary,and allows individual peaking of each band.The mechanicalconstruction is such that guying is not ordinarily needed.If the 75 meter resonator is attached to the 4-BTV,it may be desirable to guy the antenna above the 20 meter trap with small diameter polypropylenerope.The performance provided by the Hustler 4-BTV is better than any other antenna of this type.Broadbanding is such that one measurement and setting permits both phone and CW operation.The antennaprovides a nominal 52 ohm base impedance when installed and tuned according to the instructions.Theradiation efficiency is equivalent to,or greater than,other trap verticals.STEP-BY-STEP ASSEMBLY:1.Check the parts against the package contents listed on the following page.2.Install mounting bracket on the support mast or stake.Tighten "U"bolts securely.Use lockwashers and 1/4"-20 hex nuts (heavy nuts).Use 1-1/4"I.D.water pipe or other very strongsupport3.Accurately cut radial lengths (if needed or desired)in accordance with radial length table (Fig.6）.4260-1
