TECHNICAL DATA SHEET
Document Number: TM-INVERTED-VEE-001 Rev A Equipment: INVERTED VEE DIPOLE ANTENNA Classification: UNCLASSIFIED — Amateur Radio / Field Use Date: 2026-05-24 Supersedes: None (initial issue)
RECORD OF CHANGES
| Change No. | Rev | Date | Description | By |
|---|---|---|---|---|
| 1 | A | 2026-05-24 | Initial formatted release | M. Martin |
Bands: 80M, 40M, 20M Approach: V-shaped dipole, center-fed at apex Compaction: 30%
CHAPTER 1 — DESCRIPTION
V-shaped dipole, center-fed at apex
Special parameters: 45–60° apex angle, lower impedance vs horizontal
CHAPTER 2 — TECHNICAL CHARACTERISTICS
| Parameter | Value |
|---|---|
| Frequency bands | 80M, 40M, 20M |
| Feedpoint impedance | 50–600Ω |
| SWR target | <2:1 |
| Efficiency | 75–95% |
| Gain | 2–12 dBi |
CHAPTER 3 — FABRICATION
- Fabricate wire radiators per NEC model dimensions
- Install tuning elements if applicable
- Construct feed network and matching
- Measure impedance at feed point
- Tune for minimum SWR using dip meter
- Test with transmitter (low power initially)
- Verify SWR and radiation pattern
CHAPTER 4 — TESTING
Use SWR meter and dip meter to verify resonance and impedance matching.
