Does anyone make a 2m/70cm/33cm antenna?

[iceman977th]

As the title says.. I am looking for an antenna that will cover 2m, 70cm, and 33cm all in one antenna, if possible. I have seen 2m/70cm/23cm (146/440/1200) but I really need one that is more optimized for 33cm (900MHz) if possible. This is actually not for ham radio, but 2m and 33cm are close enough to the bands I need it for (railroad voice and ATCS data) as I plan on putting up a single antenna at one site to cover both with a diplexer to split the signal (there is existing coax that we plan on using which is why I am asking)

Why is my post moved to the Commercial forum? I'm asking about amateur antennas, but it's not designated for a ham radio use. Can we quit moving posts willy-nilly? There's a reason I posted it in the ham radio section..

I think this is as close as you are going to get:

The VHF and UHF sides are tuned for the commercial segment of the band, but I think you'll find that SWR is acceptable on the 2 meter/70cm band. Since it's 1/4 wave on VHF, it's probably going to have enough bandwidth to do well.

Would be interesting to have someone who owns one put it on an analyzer and see how it looks at 2m, 70cm and 900MHz.

I'd say that is the only antenna that will do both decently well, but don't expect great performance.

the reason is probably because what you are asking for is more along the lines of a multi band commercial antenna due to the fact there is no antenna that made for that in the ham ranges

Would a discone work? Or maybe this?

It sure would. The OP never stated if they were looking for mobile or base antenna.
Drawback is that the discone has zero gain and funky radiation patterns. Might work fine, though.

Or maybe this?

That antenna is 2 meter, 70 centimeter and 23 centimeters. 23 Centimeters is the 1240MHz band. OP was looking for something close to the 33 centimeter band, which is 900MHz.

The OP would be much better off with a dedicated 160MHz and 900MHz antenna with diplexer. Using a 2m antenna on VHF RR is usually grim where the antenna gain has fallen off drastically that far out of band. A diplexer for VHF and 900 is super easy and not very expensive. There were a bunch of surplus 900MHz high gain base antennas on Ebay recently for a really cheap price, I almost bought a couple but I'm a bit overstocked right now.

I use a Motorola AN000131A01 tri-band antenna that covers all three bands:

The PCTeL PCTWSLMR is basically the same antenna:

These antennas preform well on all bands. Physics is physics individual dedicated single band antennas will work better but these are a good single antenna that covers what you are looking for.

Can confirm this is a good antenna for mobile operations. I was running 5/8 wave VHF, UHF, and 7/800 antennas until I smacked a low hanging tree branch with the VHF antenna. Totally killed a 6 meter antenna at the same time. I use pretty much all bands from VHF low to 7/800 in both ham and public service. After trying out the all band antenna I’ll say it works much better than I expected on VHF; I’ll go as far as saying it works unusually well.... almost too well and it is much shorter than the 5/8 wave. I’ve only been in one situation where the 5/8 out performed the full spectrum antenna. On UHF it is okay but nothing to write home about - a 5/8 wave will definitely do you better on UHF if you plan to use any very distant repeaters. On 900 it ain’t bad but if you’re using analog and less than 30 watts again go 5/8 because you’re going to need all the oomph you can get. 7/800 on p25 it is excellent. With that being said if you want to use one NMO antenna it indeed will do it all just don’t expect it to do what a dedicated 5/8 wave antenna will do. To end I’ll say it is a very good option and it is likely it will cover all your needs. I live in very rural Appalachia and it does things I didn’t expect it to do - actually rather well. Definitely worth a try and if you look on eBay you can find them for not so expensive; the Harris full spectrum antenna is also an excellent option no real differences between them in terms of performance.
