Yes, it was odd that the HT came with a telescopic antenna. How does one know if an antenna is matched to a radio? If I bought a compact two-meter mobile antenna from a well reputable company that was about 10 inches tall, I would expect it to at least perform decently for it’s size and give my radio a good SWR.

You’ve admitted you haven’t accurately measured SWR so we now know that these antennas may, indeed, be a perfect match for the radio they were designed for. Please remember that these were mW HTs.

I followed the instructions on the page and the radio has always worked alright for its price point. HandBooks contain great info on transmission lines, SWR, and line loss. No, not at all. Of course, which would pretty much be a requirement with a mW HT with a shortened antenna. I’ve designed vhf transmitters to load into 1.

I realized that I could hit all of my nearby repeaters with 50mW on low, in fact, I could hit repeaters on 50mW that I couldn’t manyal with mW with just the plain whip. Why did Alinco do it?

Again what is resonance?

They were very small antennas, yes, both short and narrow, and a small antenna is not going to outperform a larger one. President Midland Uniden Zodiac. I just didn’t design them alinxo 50 ohms in mind.

After all, if you want a radio transceiver to reach any sort of distance, get one that will do what you want. Icom was going to put out the T82A, but because they felt that the radio didn’t live up to the “Icom Aliinco, they scraped it.

There must be something else going on. I’m just curious to what other amateurs have thought about this radio. I use a d-s11 scooter and the low power does not interfer with the electronic controler.

It’s the only model I’ve seen out there with this feature. I owned mine for about five years and used it pretty much every day with no complaints at all. I also was curious what everybody had to say about this radio that’s owned it or familiar with it.

I’m well satisfied with my DJ-S Over the past 20 years or so, several of the ARRL Antenna Compendiums have contained articles about this very subject. You guys have defenatly raised lots of good points.
