can the antenna for 340 be used by 1310?

[xiaoliangyue]

Hi,

a customer deployed Aironet 340 with WISP24015PTNF WISPerformance Series Enclosed Yagi Antenna

I searched the antenna, here're some parameters

Electrical Specifications

Frequency Range 2.4-2.48 GHz

Front to Back Ratio 30 dB

Horizontal Beamwidth 30?

Nominal Gain 15 dBi

Vertical Beamwidth 30?

Mechanical Specifications

Cable 18" coax

Dimensions 14" L x 3" OD

Equivalent Flat Plate Area 0.20 sq. ft.

Lateral Thrust 18.3 lbs

Wind Loading 1 lb

The customer is intended to replace Aironet 340 with AIR-BR1310G-A-K9-T, however keeps the old antennas.

From Cisco Website, I got following info about 1310's antenna.

Antennas for the Cisco Aironet 1300 Series Outdoor Access Point or Bridge with RP-TNC Type Connector

Product Number

Product Description

AIR-ANT2414S-R1

Cisco Aironet 2.4-GHz, 14-dBi sector antenna

AIR-ANT2506

Cisco Aironet 2.4-GHz, 5.2-dBi omnidirectional mast-mount antenna

AIR-ANT241201

Cisco Aironet 2.4-GHz, 12-dBi omnidirectional mast-mount antenna

AIR-ANT19491

Cisco Aironet 2.4-GHz, 13.5-dBi Yagi antenna

AIR-ANT2410Y-R

AIR-ANT33381

Cisco Aironet 2.4-GHz, 21-dBi dish antenna

AIR-ANT3549

Since Cisco doesn't list an antenna with Nominal Gain 15 dBi, I'm not sure if antenna WISP24015PTNF works with Aironet 1310?

Thanks

If the new radio has RP-TNC connectors then it will work. However, be advised that those antennas are old enough to be on a 340 then they may be suspect. I would start over with new gear for my enetrprise application and take those home to test with...

It should work fine.

You should encourage the customer to at least break & reconnect each fitting from the radio to the antenna input, add new weather protectant to the outside joints (Coax-Seal ... I hate it, but it's fairly available (i.e., Radio Shack)), and usually a good idea to replace the (so-called) "lightening arrestor" periodically ... they do age, whether they're hit or not.

Also clean and re-connect the grounding to the masts and shields ... they also oxidize over time and become less effective.

If the yagi elements are bent, twisted, or otherwise out-of-shape, the antenna should be replaced.

Good Luck
