Metal Telescopic Ext Gain SMA Female Baofeng etc...


93 cm converts to about 37 inches. That's a 1/2 wave at 2 meters and has no gain. So why is it a 'gain' antenna, what's it being compared to?

Most if not all of the Chinese antennas are poorly made. This is a prime example of one. Now I have no actual experience with this antenna I have purchased several other Chinese ones in the past. Out of the three that I bought only one worked correctly and that one was the cheapest, $3.79 on Ebay. If you want a good HT antenna get a Smiley Antenna. Hand made in the US and work great!

Have a look at this as well http://forums.radioreference.com/amateur-radio-antennas/243550-how-spot-fake-diamond-antenna.html

So you're just guessing. Nice science there.
Yes I guess you could say that. I have been playing the Chinese game for a while with several of their HT's and antennas and based on that its my educated "guess" that this antenna is crap. Another thing, the antenna is heavy according to the search I did, I can only "guess" that it will destroy the sma connector on any HT if used over a long period of time. I base this "guess" on using a similar antenna, a Smiley 1/2 wave, on my Icom T-22h. The weight of the antenna broke the connection inside the radio. This was a BNC connector.

I've found an antenna that works well for me. It isn't any kind of 'gain' antenna, just a typical 1/4 wave on 2 meters, which will also work on 70 cm. Actually it's a bit shorter than 19 inches, something like 15 inches, but it appears to be loaded at the base. That along with a 'rat tail' does just dandy for an HT. I don't expect much from an antenna (of any kind) on an HT that you carry around with you. It's not very realistic to expect much with an HT, get used to that. Connected to a 'real-live' base type antenna I would expect the performance any other 5 watt radio would have (if your HT does 5 watts). Several manufacturers sell a 1/4 wave for an HT, pick the one you think is best.

I have used a similar telescopic antenna and although cumbersome to use it did work well. However, those telescopic antennas are very flimsy and are very easy to deform. And the before posts are also correct as with running a larger antenna you run the risk of breaking the sma jack.

I reciently broke mine and re-machined the metal mount for larger more heavy duty screws to make it more rugged. I gave up using the telescopic antenna in lieu of the Diamond NR-770 with sma adaptor.

This antenna works very well. I just have to be very carefull handling it.

Overkill? maybe in a big city, But here in my rural area it foots the bill nicely.

Good luck.
 
I just wear my aluminum foil pyramid hat. I hit ALL the repeaters. :tongue:

So far I've only tried the Nagoya 771 antenna, and it seems to work pretty well. For "stuck in a hotel" talking, a roll up slim jim from N9TAX works great. Sure, I could have built one myself, but it would have fallen apart the first time I stuck it in my suitcase. The N9TAX is built pretty tough.
