Par Electronics EF-SWL Antenna
Hello folks,
I have a question here... I recently bought one of these excellent Par Electronic EF-SWL antennas. As the supplied radiator can be disconnected and another wire be hooked onto the 9:1 transformer, I was thinking to give a go at hooking up a 150 foot length of wire that I have on hand. My question is this: in hooking up an alternate wire to the transformer, would the antenna lose its characteristics as a 1-30 MHz antenna? Would an antenna tuner then be required? Very curious for info on this. I'm afraid I don't know too terribly much about antenna theory. Thanks in advance for any help provided, Junius |

Hi,
Give Dale P. a call at PAR. He's been really good about answering questions. But, please also post his answers here, so we all can learn. I'm about to buy one also.

And for what it's worth, it's best to avoid products by RF Systems. dxAce Michigan USA |

I agree. Their stuff seems absurdly overpriced.

Par Electronics EF-SWL Antenna
It would help to know the exact model, but from what I could see from
the website, this is similar to the Palomar end-feed baluns, though you can transmit on the Par Electronics version. The performance should be similar to a long wire, but more efficient since the transformer will improve the match. Since you are not transmitting, more wire will probably improve the low end reception, though most of those ham baluns don't work well in the AM BCB or lower. junius wrote: Hello folks, I have a question here...
