Has anybody had good results with any of the replacement HT antennas on the 6m band? There seems to be a variety of tri and quad band replacement antennas that are supposed to cover 6m but I haven't found any with good reviews.

I own and maintain a very good (IMHO) six meter repeater.  It is a GE Mastr II, running 100
watts, brand new full size TX RX duplexer, 7/8 inch hardline, with a commercial antenna at 350 feet.

I have a couple of tri-band HT's and I have tried a variety of HT antennas.  NONE of them works well on six meters.  They are just too short. 

A 1/4 wave antenna on six meters is around 54 inches tall.  Shortening such an antenna so it can be mounted on a typical HT without breaking the antenna connector (especially those with SMA's) really adversely affects performance.

If you come up with anything that works well, let me know.  So far I have not.

The only thing I can think of is similar to a 4 metre whip I got for my Wouxon, shame about it is the company that makes them do not do a version for 6 metres (DOH!!)
I dont know if anyone could roll one themselves?
The 4 metre one is approx 20 inches long with a loading coil about 8 inches up. Works a treat. Now the only problem I can see is would it have enough bandwidth?

Thanks to you both.

Dick,
When I did a search on the subject I seem to remember that you mentioned having an antenna that was about 30" that performed well, is that not the case?

Antenna efficiency has always been one of the major problems with handhelds operating int the
VHF-LO band (30 - 50 MHz).

I have a 6m HT (converted commercial unit) that I haven't tried yet, but I'm considering using
a Larsen 2m 5/8 wave whip on it.  The whips are also resonant near 6m.  I have a couple of
the whips that fit a SO-238 socket, and can adapt them down to a BNC to fit the radio.  Otherwise
I'd use as long of a whip as possible (at least 36") with a tapped base loading coil and a hanging
radial wire (possibly also loaded at the feedpoint.)

I guess "well" is relative.  It performs better than any other six meter HT antenna I tried.  It does not perform nearly as well as a 19 inch whip does on two meters, everything else being equal.

Bottom line is I am not happy with ANY of the six meter HT antennas I have tried.  However this one is better than the rest.
