My first external base antenna was a J-pole. Back when I first got my ham ticket, one of the local ham clubs would produce them en-mass and sell them at the local hamster meetup for around $35 back in the late 1980's/early 1990's, if I recall correctly.

Aluminum parts and pretty well built. I was happy with it since all I had at the time was a hand held radio and that didn't work well inside the house.
So, anything outside, even connected with cheap coax, worked much better than the stock rubber duckie on top of the radio. In my very limited experience at the time, the J-pole was the greatest thing ever since it really opened up the capability of that little radio.

As time went on, I moved up to a 50 watt mobile in the house and got a better antenna, better coax, increased height. Realized that while the J-pole worked well, it wasn't all that great an antenna.

When looking at reviews on the internet, you have got to consider what the reviewer is actually comparing the antenna to. Most of the ham reviews I see look a lot like this is the only external antenna they have ever owned and their glowing reviews are only compared to a rubber duckie on top of a $15 CCR from inside their basement.

A J-pole is a 1/2 wave end fed radiator with a 1/4 wavelength matching line. The matching line is trimmed to match the 2,500+ ohm impedance of the end fed 1/2 wave radiator to a 50 ohm feedline. The matching line should not radiate as it is a transmission line for its full length leaving the 1/2 wave section as the main radiator. There are problems with this antenna like common mode current on the feedline and having the feedline or metal mast unbalance everything. But its a popular antenna for some unknown reason and people use them despite the problems.
i know guys that swear by j poles. and we are on same thig,they cant hear what i can
