![]() Can any of you antenna pros out there tell me what would be the expected life span for a Cell Wave 4 element vertical dipole? Do not have the model number but the cost was close to $600 when purchased. The antenna is cut for 2 meters. Realize that a number of factors can be involved such as weather conditions, area installed etc. In this case it is up 80' off ground level and 300' above sea level just outside of WashDC. Second question. I recognize that Cellwave has an excellent reputation. Are there any other antenna companies that may compare or exceed Cellwave antenna products in performance and durability? Thanks. 73 Murray, K3BEQ |

![]() Can any of you antenna pros out there tell me what would be the expected life span for a Cell Wave 4 element vertical dipole? 1. Its "Celwave", not "Cell Wave". (Search also "RFS Celwave") 2. Celwave was formerly Phelps Dodge. 3. The model you want for 2 meters is the PD340-3. 4. A properly installed antenna with properly installed and sealed feedlines will probably last longer than you. Second question. I recognize that Cellwave has an excellent reputation. Are there any other antenna companies that may compare or exceed Cellwave antenna products in performance and durability? Other comparable manufacturer are Andrew, Sinclair, and Decibel Products. Quality is comparable amongst all. Ed WB6SAT |

![]() Thank you, however, I doubt very seriously any antenna is going to last over 70 years. But appreciate your input. Best estimate I received from those in the business of installing the antennas is in the area of 15-20 years.

Anyway, the 15-20 figure is good. If you use heliax, seal the hell properly out of all connectors, and mount the antenna and heliax very firmly, those no reason other than extremes of nature (lightning, huricane, etc,) to prevent it from lasting longer.

![]() **Still hanging in there at almost 73. Agree on the sealing. Club has a perfectionist who does electronics on boats and is a stickler on doing things right, especially sealing. Again, thank you. 73 Murray, K3BEQ ======================= "Ed G." wrote: Thank you, however, I doubt very seriously any antenna is going to last over 70 years. But appreciate your input.

There are numerous medium wave broadcast arrays in operation continuously since 1934, the year of the famous communications act of 1934, and some still stand from years earlier.

A two-meter band antenna constructed of stainless steel by a quality manufacturer should be at least as durable. 1934 was too early in the use of 2 meters to provide many examples to prove the point. I worked 26 years for a corporation which used many VHF ground planes including 2-meter types. Nearly all were supplied by Andrew Corporation. They were folded monopoles and withstood repeated lightning strikes decade after decade. They were permanent and like the broadcast antennas , they received inspections and infrequent repairs when rarely required, but they weren`t painted. Best regards, Richard Harrison, KB5WZI |

![]() In retrospect, I guess I should have clarified the sentence so that it did not encompass "any antenna". Broadcast arrays certainly were not under consideration since my question was in the arena of Amateur Radio antennas. But you are correct; they are long lasting but "mega-bucks" at today's prices. Concerning "repeated lightning strikes decade after decade" for 2 meter types. I suspect they don't make them like they used to. The particular Celwave antenna that I was concerned about is a 4 dipole vertical. The harness is inside the tube mount and totally inaccessible. Celwave no longer makes the harness nor the antenna for 2 meters. (Bottom line: Lack of sales.) However, as stated in some of the exchanges, 15-20 years for a $500-600 antenna is expected, although the guarantee was for 5 years when purchased in 1996. Ours lasted 8. Some compatible antennas today are only guaranteed for 2 years. Times and products have changed. Less for your money and that applies to most products, not necessarily amateur related, unfortunately. Again thanks for your input. The good old days; quality and durability. Wish we had em back. 73, Murray, K3BEQ Richard Harrison wrote: Murry Green, K3BEQ wrote: "---I doubt that any antenna is going to last over 70 years."
