Self-Paced Course — TELESCOPIC WHIP ANTENNA
TM-ANT-064 — Open Handout TM-ANT-064 Estimated time: 2–3 hours (reading + practice + field lab) Handout: TM-ANT-064 (telescopic/tm.html) — keep it open throughout
What You Will Be Able to Do
TLO-1: Given the required materials and tools — construct the TELESCOPIC WHIP ANTENNA per TM-ANT-064, tune it to resonance, and verify performance meets the SWR and resonance criteria stated in Chapter 7.
TLO-2: Given NanoVNA or SWR bridge measurements — interpret resonance and SWR data, apply the required calculations from Appendix A, and determine pass/fail against the stated acceptance criterion.
Scope
This manual covers design, construction, calibration, and field operation of the Telescopic Whip Antenna for amateur radio and communications use. Applicable frequency bands: 6M (50–54 MHz), 2M (144–148 MHz) via length adjustment. All calibration pro

How to Use This Course
- Work units in order.
- For each unit: read the assigned TM chapter first, then read the unit, then answer the self-check questions.
- Self-check answers are at the bottom of each unit — try before looking.
- The checkpoint at the end of each unit is a go/no-go.
- Complete the Unit 4 and Unit 5 labs with a real antenna before taking the final assessment.
- Passing score: 13/15 (87%). All calculation questions must be correct regardless of total score.
