My station today consists of :

Radios

• Kenwood TS-680S stock 100 watts
• Kenwood TS 430S 100 watts
• Kenwood TS 830 S 180 watts.
• TYT MD-2017 Dual band DMR Digital Radio 400-480 MHz / 136-174 MHz
• Baofeng UV5R Dual Band 144-148MHz 430-450MHz

Antennas

I recently developed by own antenna for the 10-15 meter band. I call it the MiHe 10-15 meter trapped vertical antenna.

• MiHe 10-15 Meter Trapped Vertical Antenna
• Frequency range: 21-29.7 MHz (15-meter and 10-meter bands)
• Height: 16 feet (4.9 meters)
• Trap location: Halfway up the antenna (8 feet or 2.4 meters from the base)
• Trap design: 5-inch copper coil wrapped around a 1.5-inch tube
• Radiation pattern: Omnidirectional (radiates equally in all directions)
• Gain: Moderate (around 3-5 dBd)
• SWR: Low (around 1.5:1 or better)

• Sigma Euro-Comm SE HF X80 Verticle Radial Free Antenna 6 to 80 meters

• Frequency VSWR

  3.5 MHz 80 m with Manual ATU 1.1

  7 MHz 40 m with ATU 1.1

  10 MHz 30 m , with ATU 1.1

  14 MHz 20 m with ATU 1.1

  18 MHz 17 m with Manual ATU 1.1

  21 MHz 15 m with ATU 1.1

  24 MHz 12 m Manual ATU 1.1

  28 MHz 10 m with ATU 1.1

  50 MHz 6 m with Manual ATU 1.1

• The SE HF X-80 has a gain of around 3-4 dBd (decibels relative to a dipole) on the higher frequency bands (20-10 meters).
• On the lower frequency bands (80-40 meters), the gain is typically around 2-3 dBd.

My thoughts between the two antennas?

I love them both! I am especially drawn to my home brew design "MiHe 10-15 meter Trapped Vertical Antenna" It's also the better choice for 10-21 meters.

MiHe 10-15 Meter Trapped Vertical Antenna:

• Designed specifically for 10-15 meters
• Trapped design allows for efficient operation on both bands
• Potential for higher gain on 10 meters due to the trap's resonance
• May require tuning or adjustment to optimize performance on each band

Sigma Euro-Comm SE HF X-80:

• A more general-purpose antenna covering 80-6 meters
• While it can operate on 10 and 15 meters, it's not really optimized for these specific bands
• It has a slightly lower gain on 10 meters compared to my own design the MiHe 10-15 Meter Trapped vertical Antenna.
• However, the Sigma Euro-Comm SE HF X 80 is more compact and has a more convenient design, with a wider frequency range so once could use just one antenna to cover all of the HF bands.
