SIMPLY THE BEST !  Time owned: more than 12 months
The Larsen 1/2 wave design gives MUCH higher performance than any other HT antenna made!
Side by side comparison with any other HT antenna shows the Larsen 1/2 wave antennas to be far superior.
Worth every penny!

440 Half wave too floppy for HT use  Time owned: 0 to 3 months
I just purchased the Larsen Kulduckie KD14-440HW for use with an Icom IC-04AT HT. The radiator is FAR too floppy for practical use with an HT. It's the limpest antenna I've ever encountered.

After adding a couple of layers of shrink tubing it improved, but became rather unsightly! In addition, the base is cumbersome and heavy.

Electrically it is a good antenna, as one would expect from a half-wave. So I will use it in a pinch should I need it. But I'm thinking maybe I should have just gotten a Diamond RH77CA dual bander instead.

Perfect for travel!  Time owned: more than 12 months
I have both the 2M and the 440 half wave Larsen HT antennas, and don't use them on HT's but rather with my FT 817, FT 7800R and more recently with my IC 7000.

Being half wave, they don't require a counterpoise, and they unscrew, making packing in a suitcase or carry on bag a snap. I use a tiny camera tripod with a small aluminum base plate I've drilled for a BNC chassis connector. I attache the plate to the top of the camera tripod, the Larsen half wave to the top, run a few ft of coax to a suitable spot and I am on the air in under a minute!

I can also use a UHF right angle connector and a
bnc adaptor and mount the antennas directly to the SO 239 coax plug on the back of the IC 7000 or FT 7800. This, plus a CUP 36 switching supply
(tiny computer switching supply sold by Morse Express for $39) is a very easy and feather weight way to go portable VHF/UHF.

The antennas are top quality, and built to last a long, long time. I've yet to break or damage one.

I've used this combination with the Larsen half wave antennas all over the USA and Australia and New Zealand. I've not found anything smaller, more portable or more effective in my 45 years of
ham radio. Good job, Larsen!

Both are great for the extra Miles!  Time owned: 0 to 3 months
Both of these 1/2 wave antennas are almost the ultimate on each band for HTs with a directly attached antenna.

Larsen fails to sell the best feature which is the base coil/transformer can be unscrewed from the radiator which makes the 2m a real 'pocket carryable' antenna...

The bonus of owning both antenna is that the 2m radiator works perfectly on 440 if only the bottom two sections are pulled out! No need to caryy the 440's radiator 'rubber duck' with you. Just carry both base sections and the 2m radiator and have at it.

Both add real dBs to your TX and RX signals as they should and forget about the groundplane because of the 1/2 length provides what the ground plane is only trying to create for any 1/4 wave.

Hard to use the 2m version in small spaces but the 440 one is onyl 16" which is not bad for the gain improvement over a duck antenna.

Get them both and know you will have the best possible signal for an attached antenna.

Even better is that can just add coax and hang them higher for even better performance without worrying about it! Just keep it away from other metal objects to avoid pattern deformation. It will be just like a vertical dipole and the high the better with good coax and good connectors.

Have fun! They WORK!
