NOTE: Please read 

all

 instructions thoroughly 

before

 proceeding to the assembly. 

 
There are parts made from fiberglass in this kit. Take normal precautions when handling any 
fiberglass material. There may be fiberglass dust, slivers or particles present when the fiberglass 
parts were manufactured. The use of typical fiberglass handling safety gear (gloves, dust mask, eye 
shield, clothing, etc.) when handling and working with fiberglass is recommended. Use a damp rag 
to wipe the parts. 

Do not

 use compressed air to clean fiberglass parts. Measures can be taken to 

reduce exposure after a person has come in contact with fiberglass. Eyes should be flushed with 
water and any area of exposed skin should be washed with soap and warm water to remove fibers. 
Clothing worn while working with fiberglass should be removed and washed separately from other 
clothing. The washing machine should be rinsed thoroughly after the exposed clothing has been 
washed. Check with your local or state safety and/or environmental agencies for more detailed 
precautions.

Guying Kit for Vertical Antennas

 - Some vertical antenna manufacturers indicate their antennas 

do not need guying. During times of high winds or ice loading, some of these vertical antennas may 
sustain damage or fail altogether. With the small amount of effort needed to install a four point 
guying system, the risk hardly seems worth taking. A four-point guying scheme provides the best 
mechanical advantage to reduce wind stress, regardless of direction. Information on guying the 
Butternut

 HF9V is included in this manual. Information on guying the Butternut

 HF9V can be 

found in the section “
