Care and Maintenance 

 
Your LDG balun is essentially maintenance-free; just be sure to observe the power limits 
discussed in this manual. Avoid getting the balun wet, unless you have waterproofed it as 
discussed above. The outer case may be cleaned as needed with a soft cloth slightly dampened in 
household cleaning solution. LDG strongly recommends that you use a good quality, properly 
installed lightning arrestor in the antenna lead.

Warranty and Service 

 
Your LDG balun is warranted against defects in parts or workmanship for one year from 
purchase. The warranty does not cover damage due to abuse or exceeding specifications. This 
warranty applies to the original purchaser only; it is not transferable. A copy of the receipt 
showing the purchaser’s name and the date of purchase must accompany units returned for 
warranty service.  All returns must be shipped to us pre-paid; we will not accept units with 
postage due. A return form is provided on our web site for your convenience.  
 
If you need to return your LDG balun to us for service, package it carefully, keeping in mind that 
we will re-use your packaging to return the unit to you. A self-addressed return-shipping label, 
while not required, will help insure speedy and accurate delivery of your repaired unit. Include a 
full description of the problem, along with your name, address and a phone number or e-mail 
address where we can reach you with any questions. Repairs average about 2 to 4 weeks. 
 
We will be glad to service your balun after the warranty period has ended. We will notify you of 
repair charges by phone or e-mail, and bill you after repairs are completed.
