Product Description

These coils have end caps of 3/8” thick Lexan. Wire supports are 3/8” diameter Lexan rod and coil.

The 400 and 600 series coils are custom designed and hand constructed in our own machine shop in Texas.

As with all GLA Systems coils the inserts in each end of the coil center post are machined from 1” hexagon brass bar.    

# 680 COIL 

The #680 HQ Coil is 6-3/8 inches in diameter and 7 inches long. It is wound with 12 Ga. wire at 4 turns per inch.

   Because of its larger diameter, shorter length and wider turn spacing the Q of the coil is higher than the #480 which improves the radiation efficiency. The #680 HQ has a total inductance of approximately 85 microhenrys which will allow 75 meter operation with a whip length of 72 inches without the use of a capacity hat. 

Adding a capacity hat will allow whip lengths as follows: 

20 Inch Hat----- 36 Inch Whip

16 Inch Hat ----- 48 Inch Whip

12 Inch Hat ----- 60 Inch Whip

These whip lengths are intended as a reference only. The length of the whip should be kept as long as practical. 

The “Higher Q” makes this coil the best choice for 40 and 75 meter operation.

  1. Improved coil for my Texas Bug Catcher. 5 Star Review

    Posted by on 29th Nov 2016

    The coil arrived well packed and in perfect condition. It installed easily and was easy to tune up. It replaced my 480XL coil that was badly damaged by a mishap with a tree at 35MPH. The 680 coil seems to me to have a little wider bandwidth tuning than my 480XL.
    Since it was on Special, I decided to upgrade to it from a 480XL

  2. Second to none!!! 5 Star Review

    These are the best Bug Catcher coils available. The build quality is second to none! Only the finest materials have been used and the attention to detail wow !!! I do run an amp in my truck but it never seems to get used anymore. The signal barefoot busts pile ups always !!!
