*Shipped only in U.S. and Canada.

A standard of unexcelled performance for more than 20 years, our world-renowned Scanner Beam has been improved to provide better directivity!

Ideal for 30-50 MHz low band reception, 54-800 MHz FM Broadcast and TV, 108-137 MHz aircraft, 137-174 MHz high band, 225-400 MHz military aircraft and satellites, 406-512 MHz UHF, and 698-960 MHz extended microwave mobile.

The major lobe pattern is directional from 100-900 MHz, non-directional outside of that range.

 HAMS NOTE: The Scanner Beam can be used for transmitting up to 25 watts on VHF/UHF with the following average VSWR: 50 MHz @ 1.9:1, 144 MHz @ 3:1, 222 MHz @3:1, and 430 MHz @ 1.5:1. 50-72 ohms nominal impedance.



May be used with inexpensive TV antenna rotator or fixed in favored direction. Local signals still come in loud and clear from all directions. Balun transformer, offset pipe and all mounting hardware included (requires TV type F connector on your coax).

Customer from Louisiana: "I have the new Scanner Beam up about 70 feet and it is picking up towns 90 miles away. During hurricane LiLi, I had 35 mile an hour winds. A tree went down in the back yard, but the antenna survived. Whatever you did to improve it, is a great antenna."

"My Grove Scanner Beam made it through hurricanes C,F and J.I estimated max winds at about 90mph." 
Jack in Florida

"We often have inquiries from customers wanting to know whether they can transmit with the Scanner Beam antenna.
I have run a series of experiments here, and the answer is yes. But although you could probably put 100 watts or more into the antennas, the little balun will only take intermittent transmissions of 10-20 watts, and VSWR will probably fluctuate over the wide frequency range which can cause the transmitter to shut down its power somewhat to avoid overheating." Bob

"The new Scanner Beam has virtually identical characteristics except for directivity; that's why we developed the new model. The old one had two main lobes displaced off center from the front of the boom by about 45 degrees so that aiming the antenna between 100-200 MHz gave false bearings. I wouldn't stack two different versions, so if you're stacking two Scanner Beams, they should be the new model. This isn't just to sell you a second antenna, but to prevent destructive interference from trying to phase two antennas with different patterns. But keep in mind, under perfect conditions, you will only gain 3 dB (1/2 an S unit) when you stack two identical antennas, but the pair will provide sharper directivity." Bob Grove
