<br /><br />The Loran C signal is at 100kHz, which means that a full-size antenna would <br />be about 2 miles long! But the signal is normally pretty strong (the <br />transmitters are several hundred KW output).<br /><br />Most Loran receivers are designed to work with a short vertical antenna (6 <br />or 8 feet high). Some may require a special antenna with a preamp built <br />in; I think you'll need to check the RX manual to make sure.<br /><br />At my house, I used to use a random wire running along the side of the <br />house and got a usable signal from the transmitter about 200 miles west of <br />me, but I recently changed to a vertical active antenna (more accurately, <br />an amplified voltage probe) that's up on the roof, and it made a dramatic <br />improvement in the quality of the signal here.<br /><br />Hope this helps...<br /><br />73,<br />John<br /><br />Well I hpoe this is what you wanted to know. Seems<br />the RX has a matching network for the small<br />antenna's on boats.<br /><br />73<br />Link
