5L-70cm 5 element 420-450MHz Yagi........$80
8 dBd gain, 31" boom, vertical or horizontal rear mount. 60 degree beam width and small size is perfect for portable during public service events, hand held or atop 2 sections of 5 ft mast, balloons and rockets, to give some gain and at the same time minimize multipath ghosting and drop outs.
Very practical for fixed point to point dedicated to a repeater or link.
N female jack. Mounts to masts up to 1.25 inches in outside diameter.
Stacking distance is 18" - make sure all the feed points are on the same side of the boom when stacking and equal coax lengths to the 2X70cm power splitter/combiner.
5LX 5 element Extension to your 5L-70cm...$65
Need 3 dB more gain? Then easily add 5 more elements to your existing 5L-70cm Yagi with this kit. Attaches to the end of the 5L boom.
10L-70cm 10 element 420-450 MHz broadband Yagi..$130
Boom length for both the 5L with 5LX extension or complete 10L is 61.5", end mount either polarity and beam width is 48 degrees.
Stacking distance is 35" - make sure all the feed points are on the same side of the boom when stacking and equal coax lengths to the splitter.
OAL Antenna Mast Clamp - MP-1.5...$30
Does your OAL 10L-70cm end mounted beam droop after being up for some time and being used by migrating birds as a roost? For portable applications, the single mast clamp that comes with the antenna is OK, but for home or link applications over time, it can loosen up. This mast clamp is solid and wont change. You can end or center mount it on the square boom and it has two clamps that accept up to a 1.5 inch OD mast.
The MP-1.5 will also accept the 5L-70cm and any 1" dia round boom beams. Round boom beams need a small piece of sand paper between the boom and the clamp to keep them from twisting.
WHEEL - Horizontal Omni Antennas.........$60
Little Wheel - 420-450 MHz
Nano Wheel - 902-928 MHz
Mini Wheel - 1240-1300 MHz
Micro Wheel - 2390-2450 MHz
220 MHz Wheel.........................$265
Big Wheel - 144-148 MHz .........$285
Wheels are also available for frequencies from 144 MHz to 5 gHz.
If you intend to stack wheels, they must be special ordered for stacking.
Dual 70cm Little Wheels made for splitter stacking...........$125

Quad 70cm Little Wheels w/phasing harness kit...................$370
Dual 902 MHz and up Wheels stacked on hard line...............$180
Quad 902 MHz and up Wheels in a radome w/splitter.............$400
Wheels give horizontally polarized omni directional radiation on the horizon with a wide vertical beam width of +/- 35 degrees and cross polarized above and below. Single 50 Ohm type N jack feed point, except on 2.4 gHz which has a SMA. Easily mounted on the top of a mast with a hose clamp around the mating coax plug as shown. Great for hanging down below a balloon and making a reflector behind another one on the ground for receiving rocket or balloon ATV directly below.

7CP-70cm circular polarized antenna........$150
Circular polarized 10 dBdc end mounted antenna.
Right hand twist is standard.
Use on the ground fixed, on a AZEL rotor or hand held for Rocket and Balloon ATV when some gain is necessary. Running a 1W TXA5-RCs transmitter on a balloon driving a Little Wheel antenna hanging down 2 ft or more, or with a reflector spaced 5 inches, will get good video to 100,000 ft and 50 miles slant range when using this antenna and a TVC-4S downconverter and TV to receive. This antenna is also recommened for amateur satellite work, portable and point to point at both ends to minimize multipath.
36 inch long boom, hand held or 1 1/4" mast clamp.
Single 50 Ohm BNC jack feed point.
TCR-23cm Corner Reflector.........$105
Broad 8 dBd gain 1240-1300 MHz antenna great for portable or point to point applications on the 23cm band.
Beamwidth is 90 degrees for easy aiming in the field.
Solid reflector cuts down on multipath ghosts vs. an omni for public service events.
Type N jack coax connection.
Mount for horizontal or vertical polarization with mast clamp that fits up to 1 1/4 inch OD diameter masts.
As pictured for vertical polarization, size is 12" wide by 9" high. Small and rugged.
Dual band Circular Polarized Helix
This broadband antenna is best used for amateur satellite work, when polarity is unknown or changes, minimize multipath, rockets, balloons, etc. Right hand twist is standard - RHCP - and matches the Wheel antenna but works with any other antenna regardless of polarization. Single 50 Ohm type N jack feed point. 1 1/4" mast clamp and end mounted.

Get 2.8 dB more gain by stacking another of the same antenna and running two equal lengths of 50 Ohm coax to each from the OAL antenna power splitter/combiner. Get 5.6 dB stacking 4 antennas. No inaccurate phasing harness necessary, just any two equal lengths of 50 Ohm coax.
These units are also 50 Ohm power dividers or combiners so you can run one antenna to two receivers. All ports use type N jacks.
