The WB2HOL Tape Measure Beam is one of the standards for transmitter hunting. The beam as provided in the kit is good for 2M but it has also been successfully scaled for use on other frequencies including 121.5 MHz (used for ELTs.)
Complete plans are also available on the WB2HOL web site.
Note: A choke balun consisting of 6 - 8 turns of coax around the beam will help reduce the pattern skew significantly. It is not shown on the plans for the WB2HOL Tape Measure Beam, but should still be added to the antenna.
The kits are $15.00 each and include the parts listed below. To order, payment can be made by check, money order, or PayPal (my email address is my PayPal ID.) The total due will be the number of kits ordered plus $4.50 for shipping. Please email me first to confirm what kits you are purchasing. My callbook address (KE6HTS) is good and my email address is: .
