вЂњThe SERIOUS HF Mobile AntennaвЂќ
вЂњCOMPLETE HF CELLPHONE ANTENNA SYSTEMSвЂќ
The GLA techniques Texas BugCatcher antenna is made from the greatest materials available. The center support rod is 1.5 inches diameter вЂњDelrinвЂќ. All coil end connectors are machined from 1 inches Brass Hexagon club. The п¬Ѓttings are tapped with 3/8-24 threads to allow connection to mast or whip. The coil cable ends are linked to the brass end п¬Ѓttings with lugs and metal bolts. This insures the perfect mechanical and electrical connection between the coil and mast or whip. The coil supports on each end are made of polycarbonate (Lexan). Center coil form supports are used on all coils for additional energy. No parts are constructed of PVC or phenolic, both of that are brittle. The coils will be the wound that is open to avoid the buildup of moisture, dirt and dust between the coil and coilform. All GLA masts are made of 3/4 inch outside diameter metal tubing with stainless steel threaded inserts welded in each end. All masts have actually 3/8-24 threads that are female each end. A stainless steel threaded stud is given to each end to allow connection to the majority of any type mount. The capability caps are produced from aircraft type 2024-T4 aluminum.
The вЂњTexas BugCatcherвЂќ antenna can be put together to satisfy nearly every technical conп¬Ѓguration essential to п¬Ѓt a specific installation. Nevertheless it is essential to keep in mind that the center loaded antenna has got the highest theoretical radiation efп¬Ѓciency ( as much as 50% more than the same base loaded system). With this thought, we highly recommend a mast that is base of to 5 legs and a whip length of 4 to 8 legs.Variations using this range will nevertheless offer excellent results but must be utilized only when installation demands prohibit real center loading. Whenever selecting mast length, consideration must certanly be provided to several factors. A mast should really be utilized that may permit the base of the coil become at least 6 inches over the r f for the automobile. Additionally it is essential to help keep the coil as far above ground as feasible to cut back ground losses. This should be risen to 12 inches in the event that edge of the r f is near to the coil because will be the instance with vans, suburbans and other вЂњsport utilityвЂќ type vehicles. The thing that is important keep in mind is the fact that Texas BugCatcher are put together to п¬Ѓ t YOUR particular car so when precisely tuned will give exceptional performance on all bands. We now have systems getting used with great success from as short as 7 feet as much as lengths of 15 feet on mobile installations and considerably longer for п¬Ѓxed usage. All GLA Systems coils are designed with both top performance and durability being a priority that is top. It is impossible to protect all possibilities in this space that is limited develop we could provide you with sufficient information to assist you design your Texas BugCatcher.
Texas BugCatcher Antenna
Installation Will Contain the parts that are following
WHIP 1/8 IN OR 3/16 IN DiameterEither could be custom cut to desired size
CAPACITY HAT Optional.. Depends on Coil size, Whip length and desired regularity
LOADING COIL Select according to operating regularity and level of efп¬Ѓciency desired
MAST Select mast length to insure base of loading coil reaches least 6 inches above r f of vehicle. 12 inches above r f if loading coil is within 2 feet of body of automobile. For top performance mast ought to be at the least 3 legs very long
MATCHING COIL HD-80 for 10 – 160 Meters
MOUNT A mount is employed to isolate the antenna from ground. A ball stud or mount type mount is acceptable but must certanly be as strong as you are able to.
CORONA BALL 3/4 inch diameter corona balls can be found when needed for high energy operation (over 300 watts)
EXTENDER MAST 6 inches – 12 inches could be used to raise ability hat above coil.
COIL TAPS Banana Plug TapsAdditional banana jack type coil clips with banana plug type jumpers is purchased in order to make coil tapping simpler and faster.
QUICK-DISCONNECTS Quick-disconnects can be utilized above or underneath the coil or at the base of the mast allowing removal that is easy of antenna.
SPECIAL BRACKETS Some variety of special bracket can be required Trailer Hitch Bracket, Fold-Over Trailer Hitch Bracket, Van or Suburban Bracket, Tire Carrier Bracket, 3-Way Mirror Bracket, Lexan Mast help
400 and 600 Series Coils
These coils have end caps of 3/8вЂќ thick Lexan. Wire supports are 3/8вЂќ diameter Lexan rod and coil.The 400 and 600 series coils are custom designed and hand constructed in our very own machine shop in Texas.As with all GLA Systems coils the inserts in each end of this coil center post are machined from 1вЂќ hexagon metal bar. These coils are 4-3/8 inches in diameter and 7 inches very long. They have been wound with 12 Ga. wire at 6 turns per inches. The larger diameter along with the shorter length provides a higher вЂњQвЂќ which improves the entire performance on all bands. The # 480 COIL The #480 coil has 85 microhenrys of inductance and will load in 75 meters with a whip length of 72 ins minus the addition of a ability hat. When using a capacity hat MINIMAL whip lengths will be as follows 20 inch hat—– 36 inch whip16 inches hat—– 48 inch whip12 inches hat —- 59 inch whipThese whip lengths are intended as being a guide only. the whip is kept as long as practical. # 440 COILThe # 440 is 4-3/8 ins in diameter but just 4 ins long. The # 440 coil gets the same technical and electric benefits as the # 480 coil. Because of its shorter length it’s an choice that is excellent 75 meter operation just isn’t desired. The #440 coil has 40 microhenrys of inductance and can enable 40 meter procedure having a whip as short as 59 ins
