Contact Us Your better off looking into a dipole in your attic or even looking at the dual firestick dipole. But IMO. I wouldn't waste my money on that TRAM 1499 antenna. You can't make yup for physical height of the antenna itself. A 1/2 wave antenna is approx 18ft long. The one you snow there is only 3FT long. Product Overview. Reduce precipitation static and lower background noise with the Tram Amateur Dual-Band Antenna. This 8 ft., 2-section antenna features a heavy-duty fiberglass base station, an insulated conductor, a 144-148 MHz /440-450 MHz frequency range, 6 dBd gain VHF/8 dBd gain UHF, and a power capacity of 200-Watt. The Tram 1410 is a standard discone antenna. It has no gain, but it will provide flat response coverage from 2 Meters through 930 MHz. Yes, it can receive higher and lower, but it is truly only good for about 130-950 MHz. Remember, it is broad-band and omni-directional, but has ZERO GAIN over a dipole. It was cheap for the specs, but mostly it has unclear instructions. (admittedly that may be my fault). I missed making the internal connections of the sections. worked well anyway until Winter and it filled with water. Something else I discovered TRAM 1481 is no longer made out of fiberglass as in the pass, it's PVC most likely in an Reduce your precipitation static and lower your background noise with the Tram Amateur Dual-Band Antenna.

The TRAM Unit slides along a 2"x2" or 50x50mm grade 304 stainless steel square tubing that is referred to as the TRAM Rail. The rail is supported by stainless steel Rail Cleats which are welded to the rail at 8 foot (2400mm) centers or less! IMPORTANT! When the mount bloc
