After putting on numerous antenna workshops prior to transmitter hunts, it bccame apparent that the basic antenna was not sufficient for hunting without either a receiver that included a built in attenuator, or an external attenutor. And thus The Complete WB2HOL Tape Measure Beam was born. It is the basic WB2HOL Tape Measure Beam kit, but also includes an enclosure with offset attenuator, power switch, and an output BNC connector.
The only additional thing you will need is a length of 50 ohm cable (RG-58 or RG-174 is what we use) with a BNC connector on one end, and the appropriate connector for attaching to your radio. The 9V battery is included.
As with the Tape Measure Beam kit, the kit can be built with a screwdriver and soldering iron in less than 30 minutes depending on your assembly skills. To make it simple to build, the attenuator and enclosure is furnished as a complete assembly as shown in the bottom of the photo.
The parts included in the kit are:
|1||Assembled/Tested Offset attenuator w/enclosure|
|1||11 1/2" Schedule 40 PVC Pipe|
|1||5" 1/2" Schedule 40 PVC Pipe w/18" of Gaffers Tape|
|1||1/2" Tee, Schedule 30|
|2||#12 Stainless Hose Clamps|
|1||1" Tape Measure Reflector|
|2||1" Tape Measure Driven Elements|
|1||1" Tape Measure Director|
|1||5" Wire (hairpin match)|
|8"||Gaffers Tape (for element ends protection)|
Price - $79.00 each
Postage - $8.00 USPS Priority Mail w/Delivery Confirmation
If ordering more than one, check before ordering to find out what the postage costs will be.
When ordering, I need to know if you want the attenuator with a 2 MHz offset or a 4 MHz offset. The 2 MHz offset is normally used with older radios that won't tune out of band, and the 4 MHz offset for everything else.
