VHF antennas

Omega-Tec, a company located in Jackson, MS. has just announced
that a new product line of VHF and UFH antennas has just been
released for sale. I have no financial interest in the company
but I am very familiar with the CEO and RF Design Engineer and
have worked with them for many years on other antenna projects. Omega Tec will be coming out with a line of NVIS and extended range HF antennas later on this year.Note: They are in the process of getting a web site up and I'll post that info as soon as it's available. Regards, Jim Rodenkirch K9JWV
1. The antenna(s) require no configuration or other adjustment
by the user.

2. The size of the Omega-Tec antennas is similar to the typical
OEM “rubber” antenna in length and is flexible over most of its
length.

3. There is a slight “uniqueness” about this antenna in that it
is a “multi-mode, dipole/mono-pole”antenna that is designed for
use on a handheld VHF transceiver; i.e., combining the use of
an extremely electrically short vertical dipole with a loaded
mono-pole on a handheld VHF transceiver is unique.

4. The Omega-Tec Antennas are approximately 8.5” from base to
tip.

5. The connectors currently in use are male and female SMA units
that were selected for compatibility with a large population
of 2 meter Amateur and commercial VHF-High band. Omega Tec
can outfit the antennas with BNC style connectors if there is
enough interest in that sort of connector termination.

Current product offering(s)
2-meter VHF Antenna• Frequency:144-148 MHz
• Delivers slightly more than twice the effective radiated
power of typical OEM standard ‘rubber type” antennas.
• Center frequency SWR of (typically) 1.25:1
• 2:1 SWR bandwidth of 11 MHZ
• The feed point impedance is nominally 50 ohms at the operating frequency.
• 3 db gain over the typical OEM antenna

VHF Antenna (Center Freq: 220 MHz)• Frequency:215-225 Mhz
• Delivers slightly more than twice the effective radiated
power of typical OEM standard ‘rubber type” antennas.
• Center frequency SWR of (typically) 1.25:1
• 2:1 SWR bandwidth of 20 MHZ
•The feed point impedance is nominally 50 ohms at the operating
frequency.
• 3 db gain over the typical OEM antenna

UHF Antenna• Frequency:450-470 MHz
• Delivers slightly more than twice the effective radiated
power of typical OEM standard ‘rubber type” antennas.
• Center frequency SWR of (typically) 1.25:1
• 2:1 SWR bandwidth of 20 MHZ
• The feed point impedance is nominally 50 ohms at the operating
frequency.
• 3 db gain over the typical OEM antenna

If interested, contact Lindsay at 601-855-0002, for info and
