UHF Slot antenna,700 MHz antenna,mobile TV antenna

RF Technologies is introducing several innovative antenna products at NAB 2007. We are adding two new models to our industry-leading
line up of low RFR antenna systems.

The lower power side mount SFNstar™ antennas (band IV) are now available in sectionalized models. This makes deploying the
antennas easier in building mounted applications, and reduces shipping costs. Compared to similar sized standard slot antennas,
these antennas have up to 35 dB less radiation at high depression angles. Horizontal, elliptical, and circular polarized models are
available. These antennas are great for SFN, 700 MHz, mobile TV/media, and field deployable networks.

Our SFNstar™ technology is now available in our TPV series of high band (Band III) pylon antennas. The TPV-SFN is the first VHF
pylon antenna to reduce high axial angle RFR by 15 to 25 dB as compared to similar sized standard antennas. The TPV-SFN antennas
are available in top or side mounted models, in horizontal, elliptical, or circular polarization. With the addition of the TPV-SFN antenna,
we now offer a complete line of low RFR VHF (Band I, III) pylon, batwing and panel antennas.

If you are looking for more than a standard catalog solution for your next antenna, or have trouble finding a solution to meet MPE
RFR limits at your site, we are the company you should be talking to. We are the leaders in low RFR antenna technology.

In addition to the manufacturing operation, the facility
has an expanded R&D lab area for antennas, high
power RF heating systems, and components.

RFT has called the historic mill city of Lewiston home
since it’s inception in 1991. Located 35 miles North
of Portland, Lewiston and its twin city across the
Androscoggin River of Auburn are often referred to
as “L-A” by local residents. The new facility is located
at 1 Gendron Drive, just a few moments from the
Maine Turnpike.

KRMA-DT in Denver recently selected RF Technologies to supply its ultra low downward radiation SFNstar™ antenna for the station’s
new Mt. Morrison transmitter site. The new antenna is going to be mounted on the site’s ice bridge just 39 feet above ground level.
The 32 element patent issued and pending, SFNstar™ antenna has less than 0.005 of peak field at -90 degrees below the horizon, and
less than 0.024 of peak field from -45 to -90 degrees below the horizon. With the 115 kW ERP of KRMA-DT, the antenna produces less
than 0.35% of maximum occupied exposure, and less than 1.75% of the maximum public exposure level on the ground near the antenna.

The transmitter site is located on Mt. Mansfield, which is well known for its extreme winter weather, and winds. The site is also
in a public access area with stringent ground level RFR regulations. The UHF portion of antenna pylon uses RFT’s patent
pending SFNstar™ antenna technology. This special slot antenna technology produces up to 25 dB less of radiation at high
depression angles as compared to similar sized standard slot antennas. The use of this unique antenna technology allows
WFFF-DT to operate at full ERP and comply with all RFR exposure limits.

We are the broadcast industry leader in low RFR pylon antenna designs. In addition to our SFNstar™ technology designs for
UHF (Band V), we recently introduced the TPV-SFN VHF pylon antenna for high band VHF (Band III). RFT also offers low RFR
VHF batwing antennas (Band I, III), and VHF (Band I, III) panel antennas.

RF Technologies was recently selected to provide a custom designed stacked antenna pylon for WVNY-DT and WFFF-DT in
Burlington,Vermont. The 54 foot high antenna pylon consists of a VHF high-band slot antenna, with a SFNstar ™ UHF slot antenna
mounted above it.

The transmitter site is located on Mt. Mansfield, which is well known for its extreme winter weather, and winds. The site is also in a
public access area with stringent ground level RFR regulations. The UHF portion of antenna pylon uses RFT’s patent pending
SFNstar™ antenna technology. This special slot antenna technology produces up to 25 dB less of radiation at high depression angles
as compared to similar sized standard slot antennas. The use of this unique antenna technology allows WFFF-DT to operate at full
ERP and comply with all RFR exposure limits.

We make a complete line of UHF transmitting antennas for the upper and lower 700 MHz bands for
Mobile TV applications. The products include slotted coaxial antennas, wideband panel antennas, and
our patented SFNstar™ series of low RFR slot antennas. We have a wide variety of mounting options
for these antennas and can also build them for harsh environments (icing and high wind zones).

CS 700 Series – Slotted Coaxial Antennas
The CS 700 series of antenna is a standard slotted coaxial antenna with a 6 or 8 MHz bandwidth. that is
available in a wide variety of azimuth patterns. The elevation patterns can be customized to meet site
requirements. These lightweight – low wind profile antennas can be top or side mounted. Low V.S.W.R
and group delay specifications make this antenna ideal for Mobile TV transmissions from 400 to 1700
MHz. Available in Horizontal or Circular polarization. Power input ratings from 4 to 50 kW are available

SFNstar700™ Series – Low RFR Antennas
The SFNstar700™ series of antennas uses our patented technology to reduce high axial RFR by up to 30 dB as compared to standard slotted antennas. This allows placement closer to occupied public areas and greatly reduces intermodulation problems in multi-user Mobile TV / Public safety facilities. The SFNstar700™ is available in a wide range of azimuth patterns. Available in horizontal or circular polarization. These antennas can be customized for harsh environments like icing and high wind zones. Power input ratings from 4 to 50 kW are available.

UP700 Series – Wideband Panel Antennas
The UP700 series of antennas are broadband panel antennas to cover both the upper and lower 700 MHz bands. Each antenna consists of 4 half wave spaced elements with a back plane reflector. Each antenna is radome protected. The UP700 series is available in a number of top and side mounting options. Omni-directional and several azimuth patterns are available. The UP700 is smaller than many competitive products to lower wind area and to improve omni-directional azimuth response.
