[HamWAN PSDR] Inexpensive heavy-duty wall offset mounts?

I'd like to get a few masts up without drilling holes through my roof so I'm looking at offset wall mounts like https://www.bairdmounts.com/products/wireless/complete-list/Wall-Mounts/WL-4... to clear the roof eaves. I don't feel like spending $200 per mount though. I'm looking to do 3 masts up, plus a length of unistrut across all 3 masts. Plan is to have a grid antenna for GOES, a discone, a 3' vertical for ADS-B, a Diamond X50NA, and a Mikrotik dish stuck way up high. If there are mounts that can support this that aren't $200/ea I'd be very happy. Otherwise I guess strapping the masts to the house and sticking them through the roof with boots is the way to go.
