We have a number of 2-3ft single-pol 5ghz antennas sitting around the shop, and in many cases prefer not to pair them up into a dual-pol peanut on the tower.
For more robust antennas like Radiowaves/Andrews, the options to replace the feedhorn to turn them into a dual-pol model range from $300-600 USD, which is sometimes double the cost of a complete antenna from a more inexpensive / basic manufacturer. Given that feedhorns have a similar design and purpose, just differences in mounting, I was wondering if anyone (...Chuck?) has ever heard of generic feedhorns that would allow re-using these dishes at a more reasonable cost. Commscope Andrew "grey bulb" 2ft (P2F-52-NXA or similar): DP feedhorn 115710-1 is ~$400 USD Maxrad 3ft (MPR58033 or similar): no dual-pol feedhorns available Radiowaves 2ft (SP2-5.2NS or similar): DP feedhorn 101876-2 is $330-500 USD Radiowaves 3ft (SP3-5.2NS or similar) DP feedhorn 104918-3 is ~$600 USD
