Folks:

Does anyone have information on this old 432 beam I have been using for years?

It is a KLM 432-16LBX ??? or something like that.
I can't find the specs or find any literature on it.

KLM 432-16LBX???
16 elements (3 driven)
??.? dBd gain
120" (10' 0") approximate boom
20 degree??? beamwidth
NLA

There are 16 elements but three of them make up the driven element so it is the equivalent of a 14 element beam.

I remember the bandwidth was 432-436 MHz or similar unlike their log periodic antennas with a bandwidth of 420-450 MHz.

The element spacing is wide and there is a KLM sleeve balun for the three driven elements.

Does anyone have the details/comments on the KLM?

I was thinking of replacing it with an M2 440-18X or Antennas-Amplifiers PA432-14-3B.

M2 Antennas
440-18x
18 elements
14.3 dBd gain
135"(11' 3") boom
27 degree beamwidth
$260

Comments on the M2?

Antennas-Amplifiers
PA432-14-3B
14 elements
14.0 dBd gain
114" (9' 6") boom
30 degree beamwidth

Comments on the Antennas-Amplifiers?

Maybe compare to DSE FO432-15RS?

Directive Systems
DSEFO432-15RS
15 elements
13.5 dBd gain
96"(8' 0") boom
30 degree beamwidth
$229 + shipping
